An Integrated Multi-Port Driven Radiating Source

S. M. Bowers and A. Hajimiri

A multi-port driven (MPD) antenna allows for the removal of RF blocks for impedance matching, power combining, and power delivery by enabling efficient radiation at the fundamental frequency from several output stages driving the antenna. A radiating source utilizing an 8-phase ring oscillator and eight power amplifiers to drive the MPD antenna at 161 GHz with a total radiated power of -2 dBm and a single element EIRP of 4.6 dBm is demonstrated in silicon with single lobe radiation patterns closely matching simulation.
