Abstract
In this paper, we introduce an automatic phase calibration loop circuit for a focused microwave thermotherapy system for those with diseases of the leg. An extended time reversal method is also introduced. The loop circuit is evaluated by measuring the phase errors at the array antenna feeding port. These measurements are compared to those without a loop. The results show that the overall phase errors are reduced enough to focus fields at a target point.
