Abstract :
Analysis of a slot-coupled patch antenna loaded with a MESFET oscillator at free-running and injection-locked states is presented. Simulation results yield the oscillating frequency and radiation power at the free-running state, and the locking range and radiation power at the injection-locked state. Experiments show the validity of the developed theory.<>
