Design of a Dual-Band Microstrip Patch Antenna for 5.9 GHz and 7.25 GHz with Enhanced Bandwidth

Due to the growing need for fast transmission and large channel capacity in 5G applications, dual band patch antennas are becoming more and more common. Additionally, it can offer a reliable and robust wireless connection in hard-to-reach places. This study explores the design of a dual-band microstrip patch antenna operating at 5.9 GHz and 7.25 GHz. The proposed antenna exhibits bandwidth enhancement, addressing the growing demand for efficient 5G communication system. The use of FR-4 as material for the substrate and copper for the patch and ground contribute to the antenna's cost-effectiveness and ease of integration. Introduction of slot in patch and ground improves antenna's performance which also allows bandwidth enhancement by adjusting the dimensions. In this paper the enhancement of bandwidth from 31 MHz to 44 MHz gives the scope for enhancing 5G communication applications such as V2X communication, satellite and radar application.
