Low-Profile and High-Gain Yagi Wire-Patch Antenna for WiMAX Applications

This letter presents the design of a low-profile, high-gain Yagi wire-patch antenna array that radiates a directional beam in the azimuthal plane within the frequency band 5.45-5.75 GHz. The elementary unit of a typical Yagi antenna is replaced by wire-patch antenna. This antenna delivers a gain of 14.8 dB at 5.6 GHz. A prototype of this modelized antenna is manufactured, and the measured performances are similar to the simulated ones.
