Abstract
As a promising terahertz (THz) radiation source, the photoconductive antenna (PCA) is often used in investigating and analyzing THz applications. In this paper, a novel geometric structure of THz PCA is proposed. The design is composed of a gallium arsenide (GaAs) substrate and a silicon (Si) hyper hemispherical lens. Several existing PCA designs are compared and analyzed, showing that the directivity and gain of the proposed work are significantly improved in 1.5∼3.5 THz , up to 15.45 dBi and 15.06 dBi. The design of electrodes and silicon hyper hemispherical lens are demonstrated in this paper. The proposed PCA is ideal for future THz wireless communication due to its great performance and simple structure.
