Design and Performance Analysis of a 1X4 Microstrip Array Antenna Incorporated with Frequency-Selective Surface for Enhanced Sub-6 GHz 5G Applications

EasyChair Preprint 14886

Abstract

A 1x4 microstrip array antenna design is proposed, integrated with a Frequency-Selective Surface (FSS) to enhance performance for Sub-6 GHz 5G applications. The proposed antenna is (136x55 mm²) and is compact and simple in design. This design meets the high data rate and signal coverage demands of next-generation wireless systems, exceeding FCC specifications for 5G applications. The antenna combines the benefits of a rectangular microstrip array and an innovative FSS reflector, enabling the use of low-cost FR-4 substrate while improving gain. Through comprehensive 3D electromagnetic simulations using Ansys HFSS, we optimized critical parameters: reflection coefficient (S11), gain, surface current distribution, radiation pattern, and VSWR (1.15). The result is a peak gain of 6.40 dB at 4.5 GHz, outperforming conventional designs. This work demonstrates the feasibility and effectiveness of FSS integration, paving the way for further research and practical applications in 5G antenna technology
