2018

Antennas are an inevitable part of telecommunication. In simplest words, it is a transducer that converts electrical energy into radio signals and vice-versa. The transmission and reception of signals among people that live at the physically inaccessible placescan communicate by wireless communication technology. Like any system, the wireless system also has a medium of operation, i.e., the atmosphere. Over the years, development in the field of communication has led to many types of antennas. One of these is the microstrip patch antenna which is fabricated on a substrate layer. Although microstrip antennas can provide sufficient gain, it cannot operate over large bandwidth. There must be some adjustments between various properties of the antenna. There must be some trade-off among the size of the radiating layer, number of slots on the layer, shape and size of the slots, etc. this paper presents a study of the work carried out on such antennas and presents a summary of further poss...

Prototype of Slotted Microstrip Patch Antenna for Multiband Application

International Journal of Engineering & Technology

In this paper a slotted microstrip patch antenna has been designed that works for two frequencies 1.42GHz and 2.65GHz. Since a microstrip patch antenna works only on one resonant frequency so converting that into a multiband patch antenna would enhance the bandwidth and also utilizes the multiple frequencies of operation. This multiband slotted patch antenna is fabricated on FR4 lossy dielectric substrate whose dielectric constant is 4.3 and height is 1.6mm. The length and width of patch are taken as 51.16mm and 39.86mm respectively. we cut out the slots so that the patch antenna works at multiple frequencies. Another advantage of presented design is it reduced the size of antenna actually required for 1.42GHz frequency. Simulation and analysis of slotted patch antenna is done by CST software. Simulation and fabrication results show that the presented antenna design characteristics meet with the standard characteristics of antenna.

Design and study of a microstrip slot antenna operating at 2.8/3.1/3.6/4.7/5.4 GHz

MATEC Web of Conferences, 2017

A novel design of a multi band microstrip antenna is presented in this work. The double modified U slots planar patch antenna is designed, simulated and fabricated to operate at 2.8 GHz (between 2.794 to 2.846 GHz), at 3.1 GHz (between 3.145 to 3.196 GHz), at 3.6 GHz (between 3.56 to 3.3.644 GHz), at 4.7 GHz (between 4.684 to 4.772 GHz) and at 5.4 GHz (between 5.423 to 5.526 GHz) for WiMAX/WLAN applications. One of the main challenges was keeping a low profile and low cost substrate (1.2mm and FR4 respectively) with penta-band frequency response without scarifying these characteristics. Each resonant frequency is accomplished by modifying each U slot and patch radiator itself. Simulations had been conducted using HFSS software and measured parameters such as reflection coefficient (S11 parameter) was performed with a vector network analyzer. Measured results confirm simulated results that the antenna could work within mentioned frequencies. Parametric study was conducted in order to study the effect of slots variation over the design.

In recent years, microstrip patch antennas have been widely used in various communication systems such as wireless sensor networks, wireless LANs and cordless phones as well as in body area network (BAN) due to their small size, low cost, lightweight, moderate gain and single hemispherical radiation pattern. In this research work, we proposed various structures having slots on both sides of the substrate to get an efficient microstrip patch antenna having single resonant frequency at 2.45 GHz of ISM band. Firstly, various parameters of the proposed patch antennas have been calculated using commercially available simulation software CST Microwave Studio and then the characteristics of the fabricated antennas are measured using Vector Network Analyser (VNA). Emphasis has been given on the miniaturization of antenna. By comparing the simulated and measured values, it is found that both results agree very well. Among the proposed structures of microstrip patch antennas, two-slot on patch gives the best performance.

International Journal of Engineering and Technology, 2017

This paper presents the utilization of slots with full and partial ground plane in rectangular Microstrip Patch Antenna (MPA). The partial ground plane has been introduced to increase the bandwidth of designed antenna. Proposed antenna is designed on FR4 glass epoxy substrate with 1.6mm thickness and dielectric constant 4.4. Designing and simulation has been carried out by using HFSS V13 software. MPA with full ground plane works on four resonant frequency bands, but the value of gain and bandwidth is less. Proposed antenna with varying partial ground plane has been designed and observed that it adorns the optimal results at ground length 12mm. The MPA with partial ground plane with ground length 12mm works on two resonant frequency bands (2.21GHz and 7.06GHz) with the value of gain (3.92dB and 4.71dB) and bandwidth (949MHz and 1030MHz) respectively. These values are at the acceptable level which meets the requirement of wireless application such as bluetooth (2.41-2.49GHz) and point to point high speed wireless communication (5.92-8.5GHz).

INTRODUCTION Microstrip patch antennas have been widely used in the field of wireless communications like mobile, radar and satellite because of its unique features such as compact size, ease of fabrication, low profile, less weight and ease of installation [2]. Now days, the antenna with multiband and wideband characteristics are more preferred in the wireless systems [3]. These antennas are capable of working on different applications when installed on wireless devices. By the use of multiband or wideband antennas a single device can be used for various wireless applications under specified range of frequencies [4]. Due to these features and large demand, microstrip antennas become a major area of research for the researchers [5]. Numerous researches have been carried out in recent years by the researchers to achieve multiband and wideband applications [6]. Slotted patch antennas are designed to achieve multiband characteristics [7]. But few drawbacks have been observed in this antenna design such as it exhibits less bandwidth and less value of gain [8]. To remove these drawbacks the work has been done on the ground plane of antenna because it acts as impedance matching circuit for the antenna [9]. Partial ground plane [10], defected ground plane [9], and slotted ground plane have been designed by many researchers to achieve wideband characteristics and high value of gain for different wireless standards [11]. These antennas can be capable of work under various wireless applications such as WiMAX, WLAN, Wi-fi, bluetooth, satellite communication and radar communication [12]. In this paper slotted rectangular patch antenna is designed for wideband applications. Proposed design is analysed for both the multiband and wideband characteristics by using full and partial ground plane. Detailed design and simulated results of proposed antenna with the variation in ground plane is discussed in section 2 and 3. II. ANTENNA DESIGN AND CONFIGURATION The proposed antenna uses the FR4 glass epoxy substrate board with the thickness of 1.6mm and dielectric constant 4.4. Proposed antenna is designed by using the frequency of 2.5GHz, which lie in the range of bluetooth application. Dimensions of the rectangular patch have been calculated by using the equations (1) to (5) as shown below [1]. By using these equations the length and width of proposed antenna is found to be 28.2mm and 36.5mm respectively. The line feeding technique is used to provide the excitation to the designed antenna and the position of feed is optimized to get a good impedance matching, hence located at the centre below the radiating element as shown in Fig. 1(a). Full ground plane with length and width equal to the dimensions of the substrate is shown in Fig. 1(b) and partial ground plane with width 45.6mm and length 10mm is shown in Fig. 1(c). In the proposed antenna design the slots has been introduced to obtain the novel structure of microstrip antenna. The exact position and the symmetry between the slots are very necessary to obtain the accurate results from the designed antenna. These slots help the antenna to exhibit multiband characteristics and are also helpful in increasing the gain and bandwidth of antenna. Process of designing the slots and positioning the slots in the
