A Broadband Microstrip Patch Antenna for C-Band Wireless Applications

Abstract

This paper presents the design of a broadband microstrip antenna for C-band wireless applications. The proposed design utilizes the gap-coupling technique and partial ground plane in the design to enhance the bandwidth of a T-shaped antenna. The antenna structure is simulated using CST microwave studio software and the dimensions of the antenna are optimized. The return loss, radiation patterns, gain, directivity, etc. are presented. The reflection coefficient of the antenna is less than −10 dB for the entire C-band and the maximum directivity of the antenna is 4.382 dBi. The presented broadband antenna is suitable for C-band applications.
