Microstrip Patch Slot Antenna Design for WiMAX and WLAN Applications

Abstract

In the world of socially active people, the need for connectivity is growing day by day. Internet which was a luxury few decades ago has now become an obligation. As the idea of shrinking the world with connectivity is intensively being realized, antennas with wider bandwidth and decreased dimensions are extensively required. In this paper, we design a microstrip patch antenna with infinite-loop slot for Wimax and WLAN applications. The antenna works in Super High Frequency (SHF) range and fits in IEEE 802.16 or Fixed WiMAX standard of communication. The infinite loop-slot has been added to increase the band of operation. Coaxial probe feeding technique has been adapted. The antenna is designed and simulated in Ansoft HFFS v.13.0 simulator. A substrate material of RogersRO4350(tm) has been used. The obtained results are verified to suit the requirements and are discussed for various applications.
