Abstract
A Yagi antenna, which is a typical directional antenna, has been designed and fabricated as a surveillance sensor. The proposed Yagi antenna satisfies the requirements as a surveillance sensor; impedance bandwidth of 7.2-8.2GHz, maximum gain of 7dBi, and 3dB beamwidth of $60^{\circ}$ in the azimuthal plane. The proposed Yagi antenna is designed with 3 directors and one driven element on a dielectric substrate. Also, a microstrip-to-CPS balun is designed and applied to the proposed antenna for balanced feeding of the dirven element. The performance of the proposed antenna has been verified by comparing the simulation and measurement results.
