Abstract
Rotman-lens is widely used in multi-beam antenna as beamforming networks which give several beam directions. Rotman-lens provides discrete beam-scanning by switching input ports. In this paper, we designed a microstrip-line-fed Rotman-lens phase shifter at 274 GHz. The Rotman-lens in this paper is designed using single layer of the multi-layer substrate used in the terahertz frequency band. The results of the simulation confirmed that the output power distributes between −10 to −15 dB. Based on these transmission characteristics obtained from the analysis, it is confirmed that directional scanning in five directions is possible with a size of approximately 5 mm square.
