Abstract

In today’s existence, the technology for communication is continuously growing. The agile achievement in ultra-broadband antennas in wireless communication is increased. A circular monopole microstrip patch antenna has been developed in this research paper. The parameters grandiose by antenna perfmonance are researched. The design is designed to achieve desired gain and bandwidth at 2.4 GHz frequency, with a defected ground system (DGS). This antenna design has been effectuated using FR-4 as the dielectric substrate with 4.3 as dielectric constant. In computer simulation technology (CST) the model monopole circular microstrip patch antenna is simulated and the results needed are achieved. The S11 parameter is obtained as -17.28 decibels which is below -10 decibel. The gain obtained at 2.4 GHz frequency is 1.730 decibel. Application in S band devices, including Wi-Max, WLAN, radio altimeter, cordless phones, wireless headphones etc., were built in this research article.
