Recently, a printed square-loop antenna (SLA) over a hybrid high impedance surface (HHIS) was reported, which can steer its beam in four directions in space using an RF switch diverting the input power to one of the four input ports of the antenna. In this letter, for the first time it is shown that the same planar antenna can be used to generate a semi… CONTINUE READING
