Estimating the Efficiency of Antennas Used as Sensors in Microwave Tissue Measurements
Abstract
A measurement-based method to evaluate the efficiency of antennas used in microwave tissue imaging is proposed. The method is versatile and, in principle, applicable to antennas operating in free space as well. Two identical antennas are employed, one transmitting and the other one receiving. A signal flow graph (SFG) is developed for the two-port network formed by the antennas and the medium between them. The medium's electrical properties …
