Miniaturization of L-Band Rectangular Patch Antenna by Using Two Rectangular Slit

This paper presents a successful designing of rectangular patch antenna with rectangular slit for microwave applications. Rectangular slits are used to miniaturization of patch antenna and enhancement of characteristics of patch antenna. This design offer proper impedance matching. This antenna has been simulated at 1.77GHz frequency using CST software. This design has shown return loss of -20.849dB and gain of 2.947dB. The proposed antenna design has good directional properties (directivity 6.002dBi) and high radiation efficiency.
