Zusammenfassung:	The analysis, design, experimental development, and test results of a high-gain pattern reconfigurable antenna array are presented. Unlike traditional phased arrays, the proposed array has a compressed footprint making it suitable for handheld device applications. The array pattern is reconfigured at 0°, 70°, and 290° in the azimuth plane with the help of low loss RF switches while the utilization of a collinear geometry allows narrow elevation plane beamwidth and high peak gain (between 9.7 and 11 dBi using FR4 material). System level analysis shows about 59% increase in signal-to-interference-plus-noise ratio level compared to omnidirectional antennas.
