A Compact Microstrip Patch Antenna for Mobile Communication Applications

Abstract

In this paper, the design and fabrication of a compact rectangular microstrip antenna (RMSA) are presented. The defected ground structure (DGS) along with T-shaped slots in patch is utilized to reduce the size of the antenna. The designed patch antenna with optimized dimensions is fabricated using FR4 substrate. Using the aforementioned methods, the antenna patch size is reduced by 25% when compared to a conventional rectangular microstrip patch antenna. The designed antenna is operating at mobile communication frequency band. The designed antenna is simulated and the simulation is performed using computer simulation technology microwave studio software. The presented antenna is compact in size and suitable for mobile devices.
