Design of a Microstrip Line Fed Slotted Patch Antenna for Wideband Communications

A very compact, high efficiency and simple micro strip patch antenna for wideband applications is presented in this communication. The design employs a slotted rectangular patch fed by a 50 ? micro strip line. The bandwidth is increased by cutting some rectangular slits on the ground plane. The antenna is designed on a small size ground plane (25 mm x 30 mm) and is simulated by a full wave electromagnetic simulator IE3D, a software package of Zeland. The impedance bandwidth at-10 dB return loss for the proposed antenna is about 35% (3.8 to 5.4 GHz) with center frequency at 4.54 GHz.
