Design and implementation of U-Slot microstrip patch antenna using co-axial feeding technique for WLAN applications

Abstract

U-slot patch antenna design and implementation are discussed in this paper for 5.5GHz WLAN use. The VSWR and S11 of this suggested construction, which is based on FDTD techniques to attain the desired specification, are computed using the Computer Simulation Technology (CST) microwave studio. The maximum bandwidth while utilizing coaxial feed is 260 MHz, which corresponds to the WLAN frequency range of 5.36-5.62 GHz, and at its center resonant frequency, the gain is 5.3 dB. This antenna is designed to be used in conjunction with the coaxial feed antenna. In order to obtain a stable VSWR and low return loss, a frequency band adjacent to the present system must be used.
