A design of on-chip terahertz horn antenna with microstrip feed

A novel and well-performed design of terahertz horn antenna with microstrip feed is presented in this paper. The overall design is divided into two separate parts and the horn antenna can better radiate signals into open space with a novel feed of graded shape supporting it. Promising results are obtained with the help of High Frequency Structure Simulator(HFSS). The antenna can work with a wide range of frequency from 718GHz to 788GHz, meanwhile, at its operating frequency, properties of return loss less than −10 dB and power gain more than 5 dB are observed. Because of the small scale of the design, the horn antenna and microstrip feed can be integrated and fabricated easily on chip with the technique of micro-electro-mechanical-system(MEMS).
