Abstract


In this paper different characteristics of patch antenna with two different Substrates’ materials have been analyzed. The initial antenna has been fabricated and tested. Rectangular slots have been etched in the radiating patch and ground. Two parasitic patches have been loaded to the antenna. Two different materials have been used in the substrate of the antenna and their impedance bandwidth and efficiency have been compared to each other. The Transmission Feed line is used to feed the antenna under consideration. The overall size of the final proposed antenna on Preperm L-450 is 10×20𝑚𝑚2. The impedance bandwidth of the proposed antenna is 5.44GHz and a return loss of 62.38 dB has been obtained at the center frequency of 16.93GHz. This antenna on the basis of its features can be used for Ku- Band communication.
