Two-port slot bowtie antenna with monolithically integrated photodiodes for THz power combining

摘要

We report a two-port slot bowtie antenna with two monolithically integrated photodiodes for THz power-combining. Numerical simulations show a $S_{11}$-parameter below-10 dB in almost the complete operation bandwidth from 200 GHz to 400 GHz. An experimental proof of concept evaluation of the fabricated power combiner with one radiating element shows a power enhancement around the ideal 3 dB in the whole J-band.
