Compact Spiral Patch Antenna for WLAN Applications

Abstract

The aim of the work is design, simulation, fabrication and measurement of spiral patch Antenna. Spiral antennas are coming under category of frequency independent antennas. This work highlights a constructed of 2.4 GHz of an“edge – fed rectangular spiral Micro strip patch antenna” for WLAN relevance where it’s mounted on FR-4 substrate with relative permittivity 4.4 and 0.16 mm of thickness. The parameters like resonant frequency, directivity, VSWR are calculated at various frequencies ranging from 2 GHz to 9.5 GHz, and the investigational outcomes displays that antenna has better  Omni-directional radiation pattern and is competent to operate at various GHz frequencies.  These spiral patch antenna can be used for Satellite Communications. Simulation has been realized by using HFSS software, and Antenna parameters like Reflection coefficient and VSWR are measured using Combinational Analyzer. The outcomes represent the consistency in fabricated & simulated antenna.
