Abstract

In this paper, an antenna with reconfigurable radiation pattern in the H-plane at 2.45 GHz for high power applications is presented. It is based on a 3 slots array in the E-plane covered partially with a wall of plasma in order to reduce the length of the slots and consequently ensure electrically a modification of the radiation pattern in the H-plane. The power distribution of the array is ensured with a power splitter.
