Design and Fabrication of Triangular Microstrip Antenna with Slots Technique for 5G Wireless Communication

Abstract

This study focused on the equilateral triangular microstrip antenna ETMSA because it has several characteristics, such as lightweight, low cost in manufacturing, and small size.  At the same time, a narrow bandwidth is one of the main disadvantages. This work suggests an ETMSA which that operated at a resonant frequency of 6.2GHz to meet a 5G applications. The CST studio simulation program is used to design the ETMSA. Several parameters such as bandwidth, radiation pattern, voltage standing wave ratio (VSWR), and input impedance were calculated. The bandwidth of the pure ETMSA at the resonance state is 2.5%. Slotting technology was used to improve the bandwidth of the proposed ETMSA. A circular and narrow plus-sign slots were designed and fabricated in the ground plane to enhance the bandwidth. Slots in ground plane can be enhanced the bandwidth up to 16% and 10% for the measured and simulated results, respectively.  Furthermore, a significant improvement as a result of a two circular, elliptical and plus sing slots in the patch is satisfied. BW percentages are 10.9% for simulated and 18% for measured, is achieved.
