Radiatively Coupled Oscillator Arrays

 

Simple patch-antenna based oscillators synchronized through antenna coupling.

Top array: 4x4 Gunn diode array
bullet9.6 GHz operation
bullet22 Watts ERP
bullet1% DC-to-RF efficiency
Bottom array: 4x4 MESFET array
bullet8.2 Ghz operation
bullet10 Watts ERP
bullet26% DC-to-RF efficiency

Proof of concept arrays, led to better understanding of coupled-oscillator systems including mutual synchronization, phase dynamics, beam scanning, and mode-locking.
