Abstract :
A circular microstrip antenna is designed in order to obtain the required parameter responses from 2.4 GHz-2.5 GHz by using GENESYS software based on the method of cavity model due of simplicity and easier to analyze. This circular patch is fed by microstrip line and RT Duroid 5870 is used with the specified information include the dielectric constant of substrate (isinr = 2.33) the resonant frequency (fr = 2.45GHz) and substrate height (h=0.5 mm). The circular microstrip antenna exhibits appropriate required parameters depend on the feed point position, size of the circular patch and length of the microstrip line. A prototype of a circular microstrip antenna has been built and tested by Vector Network Analyzer. The agreement between the measured and simulated results is slightly differ caused by several factors that would be discussed in result part.
