Abstract

In this paper, a compact planar 60-GHz CPW-fed pattern reconfigurable quasi-yagi antenna is proposed. The proposed antenna consists of CPW-fed mono-pole antenna, symmetrical shared metal plane as reflector, a pair of four thinner metal planes as directors and two PIN diodes for pattern switching ability. Based on suitable DC bias arrangement of PIN diodes, the proposed antenna can operate in either bidirectional pattern or right/left direction high gain end-fire pattern. In other words, the proposed antenna can operate as a gain enhancement mono-pole antenna or a high gain quasi-yagi antenna by means of proposed structure, achieving pattern reconfigurable ability in 60 GHz band. Simulated results exhibit good performances in terms of bandwidth, gain and pattern reconfigurable ability.
