Performance Evaluation of Microstrip Square Patch Antenna on Different Substrate Materials

The demand of small size electronic systems has been increasing for several decades. The physical size of systems is reduced due to advancements in integrated circuits. With reduction in size of electronic systems, there is also an increasing demand of small and low cost antennas. Patch antennas are one of the most attractive antennas for integrated RF front-end systems due to their compatibility with microwave integrated circuits. To fulfill the demand of integrated RF front-end systems, a design of micro strip patch antenna for 60GHz microwave applications has been introduced. This antenna maintains a maximum gain of 7.91dB for far field region with respect to paraboloidal rectangular aperture antenna. It is actually a coaxial probe fed antenna for impedance matching with 50 ohms coaxial cable. This antenna works well in the frequency 60GHz with a maximum at 60.15GHZ. It is basically a low cost, light weight, medium gain and narrow band antenna for microwave applications such as a feeding element for other antennas and in research institutes as a reference antenna. It can also be used at the output of signal conditioning circuit for receiving signals from micro electromechanical sensors.
