Performance of Terahertz Photoconductive Antennas

PAM XIAMEN offers 150-μm-gapped THz photoconductive antenna.

The types of terahertz photoconductive antennas prepared includes diope antenna,strip line antenna, bow-tie antenna and antenna array with different parameters. The antenna gaps are from 2 μm to 1 mm, and we also can make the antennas designed by the customers. The most commonly used antennas are with the gap of 100μm, 150μm and 200μm. The antennas have been installed on antenna mounts and can be connected with a bias source easily. The following table lists the main parameters of a 150-μm-gapped antenna.
