Abstract :
A two-element Yagi-Uda array with two physically equal-length slots tuned by DC bias is presented. By changing the DC bias of two reactive FET circuits imposed upon both ends of the slot, one of the two slots can be made shorter electromagnetically and serves as a director so that a two-element Yagi-Uda antenna array is achieved
