Abstract :
Summary form only given. The article describes a four microstrip Yagi-Uda antenna array. The array consists of four Yagi-Uda antennas arranged around a common reflector patch. This array is electronically steerable, having one antenna active at a time while the remaining three elements are earthed with pin diodes at their feed points. During tests the switching was done by manually swapping the feed and shorting stubs. The linear polarised radiation pattern from the array (single active antenna) at an elevation of 26 degrees above the planar array is presented.
