Design and Study of Rectangular Micro strip Patch Antenna for WLAN Applications

Abstract

In recent years, the microstrip patch  antenna has  made tremendous strides. The antennas  have greater  advantages and better opportunities compared  to  the conventionally manufactured antennas. They are slightly lighter in weight, smaller in length, low cost, smaller in sized and  simpler  to manufacture and adapt. In addition, the  microstrip patches can  provide dual and    circular polarizations, dual-frequency operations, agility level, broad  bandwidth, versatility in feed lines and omnidirectional scanning beam. The material used for substrate is FR4 epoxy, the designed antenna will cover the 5.6 GHz frequency for WLAN applications.  The  main  goal  of  this  paper  is to design the microstrip antennas that  significantly  reduces  structural complexity and hence the antenna size with a good radiation pattern. The performance parameters such as S-parameter, Gain, VSWR, directivity of the antenna is obtained and analyzed using ANSYS HFSS software.
