Multipolar Terahertz Antennas

Continuous-wave photonics-based THz sources present limited output power due to the restricted input optical power accepted by photomixers. Here, we investigate multipolar antenna design to increase the available THz output power by increasing the number of photomixers. Simulations of 4 to 8 dipole arms antennas are conducted, showing an improvement of antenna gain in comparison to standard dipole antennas, additionally to a potential increase of the THz power for photomixing applications.
