Abstract
This paper presents reconfigurable beam steering patch antenna with high gain for a wireless headset. Because existing antenna for wireless communication in headsets has an omni-directional radiation pattern, it has a deleterious effect in the vicinity of the human head. To reduce this effect, this paper proposed an antenna comprised of a U-slot and manufactured on a FR-4 substrate. The antenna operating at the 2.37-2.5 GHz band used a tapered matching method to match the impedance between the feed part and patch part. To implement the beam steering capability, the antenna used two PIN diodes. Using PIN diodes, the antenna presented three states ($S_0$, $S_1$ and $S_2$) in the maximum beam directions of the YZ-plane ($0^{\circ}$, $30^{\circ}$ and $330^{\circ}$, respectively). The peak gains of the antenna in the headset were 4.22-5.15 dBi. The fabricated antenna could communicate efficiently with a wireless headset.
