Abstract

In this paper, a new design of a wide band rectangular microstrip patch antenna in Ku-band using multilayered dielectric structure is presented for broadband RADAR and satellite applications. In this compact design, a conductor pin is used to excite the radiating patch. The parasitic patch is separated from the radiating one by air gap. The obtained 10-dB impedance bandwidth of the antenna is improved to more than 22%. The variations in the measured gain of the proposed antenna are less than 1 dB in the whole bandwidth. The simulation and fabrication results of the proposed antenna are in a good agreement.
