Abstract :
The heart of the integrated antenna and detector is the matching network between them. In this paper, four type antennas for matching the small impedances of high temperature superconducting terahertz detectors at 650GHz are proposed. And the coupling efficiency has improved for high temperature superconducting YBa2Cu2Ox (YBCO) Josephson junction detector with these antennas. Meanwhile, the array structures are designed to harvest more terahertz energy from the space. The resonant property and the coupling efficiency are measured by the terahertz time-domain spectroscopy (THz - TDS) system.
