A Hybrid Microstrip Patch Antenna with Parasitic Slot for WLAN Applications

摘要

A compact dual band microstrip patch antenna (MPA) with slot for wireless local area network (WLAN) applications is proposed. The dual-band microstrip patch antenna with slot fed by a micro strip line is designed to achieve dual frequency operation. The proposed antenna structure consists of microstrip patch resonator and C-slot resonator. The C-slot is etched on the ground plane of the microstrip patch. By adjusting the structure parameters, the microstrip patch operates at higher band (5.5 GHz) and C-slot operates at lower band (2.4 GHz), both resonators are radiating with two different radiation patterns. In order to determine the performance of the proposed antenna, functional parameters such as return loss, bandwidth, voltage standing wave ratio (VSWR), and radiation pattern are observed by the simulation of the structure with high frequency structure simulator (HFSS). The proposed antenna structure is suitable for WLAN applications.
