Design optimizes return loss and gain in a dual-substrate microstrip patch antenna, suggesting improvements for wireless systems.
This paper presents the design and simulation of a high-performance microstrip patch antenna(MSA) using a dual-substrate configuration for 2.4 GHz ISM band applications. The design incorporates two distinct dielectric materials—FR4 and Rogers RT/duroid 5880—to achieve an optimal balance between cost-effectiveness and high efficiency. Simulated using HFSS, the antenna demonstrates enhanced performance in terms of return loss, voltage standing wave ratio (VSWR), gain, bandwidth, and radiation characteristics. This study provides insights into how hybrid substrate configurations can improve microstrip antenna performance for modern wireless communication systems including Wi-Fi, Bluetooth, and Zigbee.
