Abstract
A V-band strongly-coupled single-chip MMIC oscillator array is presented. For wide bandwidth and easy biasing to push-pull type oscillators, modified 2-port microstrip parasitic coupled antennas are employed. When measured in a closed oversized waveguide, the MMIC oscillator array with two 2-port antennas and four oscillators radiated an output power of 4.4 dBm with excellent spatial power combining efficiency of 93% at 58.59 GHz.
