A compact modified hexagonal slot antenna for wideband applications

Electromagnetics, 2018

This paper explains the design and analysis of modified hexagonal slot antenna for wideband applications. The proposed antenna is fabricated on FR-4 substrate. On one side of square substrate, a square patch is printed and one hexagonal slot and six circular slots are etched. On the other side of the substrate, a rectangular microstrip line is printed to feed the antenna. High-frequency structure simulation (HFSS) software is utilized to optimize the different antenna parameters. The simulated and measured results are compared, and these are in good agreement. The proposed design and feeding technique allows the antenna to operate within the frequency range of 2.16-3.42 GHz with the fractional bandwidth of 45.16%. The broadsided gain of proposed radiator is more than 2.6 dBi. The proposed antenna is quite appropriate for IMT (2.3-2.4 GHz), Bluetooth (2.4-2.5 GHz), WLAN (2.4-2.484 GHz), and WiMAX (2.5-2.69 GHz) applications.

Jordanian Journal of Computers and Information Technology

An enhanced hexagonal shaped planar antenna is presented for ultra-wideband (UWB) applications. In this paper, a hexagonal patch with six circular cuts at its vertices is designed on FR4-substrate with 50 Ω microstrip triangular tapered feed line and a bevelled partial ground plane with five half circular sleeves. The design is investigated using the high-frequency structure simulator (HFSS). The simulated and measured scattering parameter S11 (Reflection Coefficient) results show good impedance matching in the frequency range (3-27.57 GHz) satisfying return loss (RL = |S 11 |) ≥ 10 dB with a percentage bandwidth (PBW) of 160.75%. High gain and efficiency, radiation pattern similar to the electric dipole in E-plane and good omnidirectionality in the H-plane are achieved.

Microstrip patch antennas is one of the most used antennas for wireless communication. Its key features include a limited bandwidth, low cost, and ease of manufacture. This paper describes about the design of microstrip patch antenna over the frequency range of 3.1 GHz to 10.6 GHz for UWB applications. The substrate material chosen is FR4, having a loss tangent of 0.02, dielectric constant of 4.4, and substrate thickness of 1.59 mm. This work presents design of microstrip antenna with hexagonal shaped radiating patch. An antenna is modelled and analysed using HFSS 2021 R2 software. The antenna structure provides return loss which is less than -10 dB and a VSWR less than 2 over the specified frequency range. The simulated results of proposed hexagonal shaped microstrip patch antenna provides a peak gain of 5.32 dB with radiation efficiency of 90.88%. The planned antennas can be used for UWB applications.

Progress In Electromagnetics Research C

A rigorous analysis of hexagonal slot with electromagnetically coupled parasitic element is presented in this article. The wide band feature of the antenna highly depends on the shape and location of the parasitic element and tuning stub. It is found that tuning and overlapping of resonating modes at lower frequency band are mainly achieved by parasitic element. The proposed antenna exhibits the bandwidth of 120.83% from 1.45 to 5.8 GHz for S 11 < −10 dB. The parameters of the antenna and circuit model are studied. The role of individual resonators in circuit modeling is also explained. Series of equations for lower cutoff frequency and other resonating frequencies are deduced after inspecting the surface current distribution. At frequencies 2.27, 4.17, and 5.2 GHz, the simulated and measured far fields are compared.
