Performance evaluation of a first phased array operating at 300 GHz with horn elements

The application of frequencies beyond 300 GHz in the so-called THz frequency range requires electronic beam steering, which can be realized by a phased array. In this paper, measurement results of a novel 300 GHz phased array antenna with horn elements and a targeted gain of 20.7 dBi for THz communications are presented. The results are compared to simulations with respect to antenna patterns, gain, half power beam width, frequency dependence of these and the matching of the antenna elements. An outlook towards measurements of antenna patterns of the array as a whole concludes the paper.
