Design and Comparison of Multislot Microstrip Patch Antenna for WiMAX and WLAN Application

In this work, we have proposed an inverted F-slot microstrip patch antenna design for Worldwide Interoperability for Microwave Access (WiMAX) and Wireless Local Area Network (WLAN) applications. The design is a modified version of [1] which provides better results. The radiation performance such as Voltage Standing Wave Ratio (VSWR), return loss, radiation pattern and gain of antenna are observed using Ansoft HFSS. In this we have taken [1] as a reference and modified it and then finally proposed our antenna. Microstrip feeding technique is used in our proposed antenna with FR4 epoxy substrate with dielectric constant of 4.7 and height 1.6mm. A detailed comparison of shapes and results are presented for readers. The operating frequency of proposed antenna falls in band of operation of WiMAX technology which is 2.7GHz-3.8GHz, 5.4GHz-6.0GHz.
