The Analysis, Modelling and Comparison between Circular and Rectangular Patch Antennas

Patch antennas are a type of antenna used in a lot of domains in our days, from GPS, radars and mobile phones to cancer tissue detection, spaceships, satellites and missiles. Their geometrical parameters and feeding type influence their functionality and characteristic parameters. This paper focuses on high frequency numerical modeling of circular and rectangular patch antennas with two different types of feeding. Four different types of antennas are high frequency analyzed to find their characteristic parameters. A comparation of the results obtained for the parameters of circular and rectangular patch antennas for different feeding types is detailed in order to find their influences on the frequency range in which the antenna is working.
