This work explores the possibilities of directly addressing the impedance mismatch problem in the design and modelling of a continuous wave photomixer employing high impedance antennas, based on conservative design rules and material choices. Two antenna designs derived from the folded dipole are presented and compared to published results from an existing device showing an improvement of up to 4.6 dB in output power. The possibilities of implementing a lumped element matching network are discussed.
