Capacitively-Loaded THz Dipole Antenna Designs with High Directivity and High Aperture Efficiency

摘要：

　　Several linearly polarized photoconductive terahertz antenna designs and their performance characteristics are reported.A single capacitively-loaded dipole antenna is introduced first; it has a 12.8 dB directivity, a 11.6 dB realized gain, and a 82% radiation efficiency.By connecting two single capacitively-loaded dipole antennas to form a linear array,higher directivity (14.8 dB), lower sidelobe level (-18 dB) and larger front-to-back-ratio (14 dB) values are achieved.Moreover,by incorporating a meta-film structure as a superstrate of the antenna array, some additional interesting behaviors are achieved.
