60GHz stacked Yagi Magneto-Electric Dipole antenna with wideband and high gain properties

A stacked Yagi antenna excited by a modified magneto-electric (ME) dipole is presented. The ME dipole is composed of a horizontal planar dipole and metallic vias which work as magneto dipole and the antenna is simply fed by a coaxial feed without using a balun. Simulated results indicate that the proposed antenna operates from 48 GHz to 74 GHz (S₁₁≥-10dB). Stable radiation patterns with low back radiation and gain of over 10dBi can be observed in the whole operating band. This antenna element yields advantages of wideband, high gain and low-cost fabrication.
