Microstrip patch antennas became very popular in mobile and radio wireless communication, due to ease of their analysis, fabrication, and attractive radiation characteristics. The use of Microstrip antenna in wireless communication found advantageous compared to other types of antenna due to their low fabrication cost, small size, supporting character to linear as well as circular polarization, robustness when mounted on rigid surfaces. However, they have their own limitations due to low efficiency, narrow bandwidth, surface wave loss and low gain. Electromagnetic Band Gap (EBG) materials, as superstrate is used to overcome the limitations of Microstrip patch antenna. The main aim of this paper is to implement EBG antenna and compare their characteristics at the frequency 2.4GHz using simulation. These designs are simulated using High Frequency Structure Simulator (HFSS) tool.

“…There are five main steps to design such an antenna [8], as briefly explained in the following. First, knowing the frequency bandwidth at 3 dB, we can determine the quality factor Q of the resonant cavity of a mono‐source square EBG antenna from an abacus obtained by several simulations using CST Microwave Studio.…”

This article introduces a new model of base station antenna used to communicate with mobile vehicles such as cars, trains, etc., providing high data rate for passengers on bord. This is a high gain sectoral electromagnetic band gap antenna, to limit the number of base stations along the covered way and to improve the wireless communication system. In this work, the base station antenna, which operates on the 5.47–5.725 GHz mobile WiMAX band, is designed and realized. Measurement and simulation results are shown. © 2010 Wiley Periodicals, Inc.

“…Antennas with sectoral beams are highly desired for base station applications, which are characterized by their dissimilar E‐ and H‐plane radiation patterns. To realize a high‐gain radiation pattern with wide and narrow beam‐widths in the azimuth and elevation planes, respectively, Fabry‐Pérot cavities and Electromagnetic Bandgap (EBG) structures are two of attractive approaches proposed so far . For instance, cylindrical partially reflective surfaces (PRS) have been used to design a high‐gain antenna with a broad azimuth pattern .…”

“…Another method, presented in , consists of a rectangular cavity excited by a patch antenna, which is integrated with a dual polarized metallic EBG structure to achieve a high‐gain pattern. To further increase the antenna gain and also enhance the bandwidth, a linear antenna array has been used to feed a rectangular cavity covered with a grid of parallel metallic rods . In these designs, the metallic ground planes have been used.…”

An antenna constructed with a conformal engineered reflector is presented, demonstrating an enhanced gain, shaped‐beam radiation pattern. The reflector is composed of artificial magnetic conductor (AMC) unit cells designed for the desired reflection phase responses. A methodology is developed, describing the scattering mechanism of AMC unit cells to collimate the reflected waves toward the broadside direction. Obtained results show a gain enhancement of about 7.5 dBi compared with the case where antenna is alone. Moreover, the antenna has a fan‐shape radiation beam with half power beam‐widths of 37° and 87° in the E‐ and H‐planes, respectively. Measured results show a shaped‐beam antenna with maximum gain of 9.5 dBi, and a wide impedance bandwidth ranging from 2.4 to 2.6 GHz. © 2017 Wiley Periodicals, Inc.
