TJPRC, 2014

This paper presents the design of an ultra-wide band (UWB) patch antenna with the microstrip line feed and also optimization of various antenna parameters. The antenna has been designed on a FR4 substrate with dielectric constant ℇr = 4.4, loss tangent (tan δ) = 0.002. The antenna has been optimized to obtain UWB characteristics from frequency range 3.1 GHz to 10.6 GHz. The simulation results gives the satisfactory antenna parameters over the entire frequency band. The reflection coefficient of the optimized microstrip patch antenna is below -10 dB over the entire frequency band. VSWR is also < 2 over the entire frequency range. The radiation pattern of the designed antenna is nearly omni-directional in H-plane and bi-directional in E-plane. The proposed antenna has been simulated using CAD FEKO 6.2 EM Simulator using MoM (Method of Moment). The antenna presents in this paper provides a brief idea of Ultra Wide Band RSMA. The designed antenna is comparatively smaller in size, low cost and can be used for the various UWB applications.

Modified Planar Monopole Antenna for UWB Applications

Ijca Proceedings on International Conference on Communication Circuits and Systems 2012, 2013

In this proposed paper, a planar monopole antenna with modified patch and truncated ground plane for Ultra wideband (UWB) applications is presented. The radiating element of the proposed antenna is fed by a 50 Ω microstrip line. Truncation in the ground plane is made for better impedance matching. It is found that by making steps in the ground plane, return loss characteristics and hence the VSWR is improved. The antenna parameters and performances have been investigated by using commercially available CST Microwave Studio 2012 software. Simulation and measurement results show that the proposed antenna provides an ultra wide bandwidth, completely covering the range set by the Federal Communication Commision (FCC) for UWB operations (3.1 GHz to 10.6 GHz).The antenna is of low profile and exhibits omnidirectional radiation pattern and high gain for the entire bandwidth.

Design and analysis of ultra wide band planar monopole antenna

2011

A novel two layered UWB antenna is proposed and designed to resonate at the full range of UWB frequencies' spectrums from 3.1 GHz up to 10.6 GHz, well below -14.0dB reference levels of return loss. The size of the UWB antenna is small, with width of 31.0 mm and length of 25.0 mm, and the two layers of FR4 board thickness are 0.5 mm (top layer) and 1.6 mm (bottom layer).The antenna radiates omni-directionally with different intensities at different directivities within the UWB frequency spectrums. The dual layered configuration gives the antenna additional options of being integrated with additional structures in order to perform a band rejection of a certain targeted band of frequencies, if required. The UWB antenna has also been fabricated using the same dimensions on a single layer 1.6 mm thick FR4 board and it still gives similar excellent performance.

Compact Planar Rectangular Monopole Patch Antenna for Ultra-wideband Application

A compact monopole microstrip rectangular patch antenna having defected ground plane(DGP) with notches is presented in this paper. Ultra-wide band (UWB) patch antenna is feed by microstrip line feed. Parametric study have been conducted by changing the gap distance between radiating patch and DGP and changing the feed position. Optimum results are observed when gap between the radiating patch and DGP is 0.5mm and for offset feeding of microstrip feed line. The obtained reflection coefficient is less than -10dB for a frequency range of 3GHz to 10.66 GHz. The antenna has been designed on a FR4 substrate with dielectric constant єr = 4.4, loss tangent (tan δ) = 0.02.The radiation pattern is directional in E-plane and nearly omnidirectional in H-plane. Efficiency decreases at the higher frequency edge due to the lossy substrate. The UWB antenna is simulated using CAD FEKO 6.2 suit electromagnetic simulator using MoM (Method of Moment).

Optimization of Planar Monopole Wideband Antenna for Wireless Communication System

In this paper, a new compact wideband monopole antenna is presented for wireless communication applications. This antenna comprises of a new radiating patch, a new arc-shaped strip, microstrip feed line, and a notched ground plane. The proposed radiating patch is combined with a rectangular and semi-circular patch and is integrated with a partial ground plane to provide a wide impedance bandwidth. The new arc-shaped strip between the radiating patch and microstrip feed line creates an extra surface on the patch, which helps further widen the bandwidth. Inserting one step notch on the ground plane further enhances the bandwidth. The antenna has a compact size of 16×20×1.6mm 3. The measured result indicated that the antenna achieves a 127% bandwidth at VSWR 2, ranging from 4.9GHz to 22.1GHz. Stable radiation patterns with acceptable gain are achieved. Also, a measured bandwidth of 107.7% at VSWR 1.5 (5.1-17GHz) is obtained, which is suitable for UWB outdoor propagation. This antenna is compatible with a good number of wireless standards, including UWB band, Wimax 5.4 GHz band, MVDDS (12.2–12.7GHz), and close range radar and satellite communication in the X-band (8-12GHz), and Ku band (12-18GHz).

A small and compact triple-band microstrip-fed printed monopole antenna for Wireless Local Area Network (WLAN) and Worldwide Interoperability for Microwave Access (WiMAX) is presented. The proposed antenna consists of a rectangular radiating patch with L-and U-shaped slots and ground plane. A parametric study on the lengths of the U-and L-shaped slots of the proposed antenna is provided to obtain the required operational frequency bands-namely, WLAN (2.4/5.2/5.8 GHz) and WiMAX (2.5/3.5/5.5 GHz). The proposed antenna is small (15 15 1.6 mm ) when compared to previously well-known double-and triple-band monopole antennas. The simulation and measurement results show that the designed antenna is capable of operating over the 2.25-2.85, 3.4-4.15, and 4.45-8 GHz frequency bands while rejecting frequency ranges between these three bands. Omnidirectional radiation pattern and acceptable antenna gain are achieved over the operating bands.

International Journal of Communication

A new microstrip-fed monopole antenna with simple planar structure of size 24×28×1.6 mm 3 is presented for ultra-wideband (UWB) applications. The antenna structure consists of V-shaped patch, microstrip-fed line and partial ground plane structure.

Simulation results confirm that the presented antenna has a large bandwidth below (S11≤ -10 dB) covering the ultrawideband frequency range of (3.15-13.2 GHz) with band notch characteristics at WLAN band. The proposed antenna creates a monopole like pattern in the E-plane and omnidirectional radiation pattern in the H-plane.

UWB monopole patch antenna with two H-shaped slots and dual-band notch for WLAN and WiMAX applications

Proceedings of the Estonian Academy of Sciences, 2021

Ultra Wide Band (UWB) denotes a wireless technology developed to transfer data at high rates over very short distances and at low power densities. In this paper, a highly miniaturized monopole antenna with a dualnotch band is presented for Wireless Local Area Network (WLAN) and Worldwide Interoperability for Microwave Access (WiMAX) systems. The overall size of the broadband antenna was reduced to 22 mm 2 × 20 mm 2 , which improved the UWB operation in the frequency range (2.4 GHz-9.6 GHz). Etching two Hshaped slots on the radiating patch of the antenna was implemented to reject the WiMAX frequency range from 3.1 GHz to 3.9 GHz and the WLAN frequency range from 5.1 GHz to 5.9 GHz. Thus, the monopole patch antenna has dual Hshaped slots etched on the radiating patch. The antenna was printed on FR4 dielectric substrate and fed by a coplanar waveguide (CPW). The coaxial feed was used to obtain an impedance matching of 50 Ω. The antenna exhibits omnidirectional and bidirectional radiation performance in the H and Eplanes, respectively. In addition, it was tested and verified in practice.

A compact monopole micro strip rectangular patch antenna having truncated ground plane(TGP) with notches is presented in this paper. Ultra-wide band (UWB) patch antenna is feed by micro strip line feed. Parametric analysis have been conducted by designing the pair of notches on both patch and ground plane, analysis by varying the distance between rectangular radiating patch and truncated ground plane, at last by obtaining micro strip feedline position.

The proposed antenna has been designed on a FR4 substrate with dielectric constant єr = 4.4, loss tangent (tan δ) = 0.02. The radiation pattern is directional in E-plane and nearly omnidirectional in H-plane. Efficiency decreases at the higher frequency edge due to the lossy substrate and it is upto 70%.
