Design of double L-slot microstrip patch antenna array for WiMAX/WLAN application using step width junction feed

摘要

In this paper, a double L-slot microstrip patch antenna array using an infinite ground plane and step width junction-feed for Worldwide Interoperability for Microwave Access (WiMAX) and Wireless Local Area Network (WLAN) applications were presented. The proposed microstrip patch antenna array consists of two rectangular patch element embedded with two L shaped slot with a compact size of 30.65mm×36.35mm×1mm. The proposed antenna was analyzed with two different feed arrangements and operates at 3.6GHz to cover the frequency bands of WLAN (2.4 to 5.8GHz) and WiMAX (2.5 to 5.5GHz) and satisfying the antenna requirements using Ansoft (HFSS). Antenna parameters such as return loss, VSWR, impedance matching and radiation pattern were analyzed. Simulated results for the designs are studied and investigated.
