Abstract
An antenna arrangement for generating and receiving terahertz radiation is described. The arrangement comprises a substrate comprising a photoconductive material and a pair of electrodes provided on the photoconductive material. Each electrode includes a plurality of elongate fingers spaced apart from each other which are arranged in a parallel relation and define finger gaps therebetween. The fingers of one electrode are located within the finger gaps formed between the spaced apart fingers of another electrode so that two neighboring fingers belong to different electrodes. The fingers of each electrode have at least one protrusion extending away from lateral sides of the fingers within the finger gap. Each protrusion is slanted with respect to the corresponding finger direction, and directed towards a neighboring slanted protrusion extending from the neighboring finger such that end edges of the neighboring protrusions extending from the neighboring fingers approximately face one another, thereby defining a protrusion gap between end edges of the facing protrusions.
