A phased array antenna with horn elements for 300 GHz communications

For THz communication systems, highly directive antennas are required to overcome the high free space path losses. For this reason, electrical beam steering is one of the key challenges for future applications. In this paper, a design for a first electrically steerable antenna operating at around 300 GHz is presented. The design is based on a phased array which consists of four horn antenna elements. A simulated total gain of 20.7 dBi was achieved.
