Open-ended rectangular waveguides as antennas for medical diagnostics.
Open-ended rectangular waveguides, potentially useful as microwave antennas for medical diagnostics are described. Reflection coefficients have been measured for the waveguides fitted with standard flanges in contact with water and skin. Antenna matching to the tissue is discussed. Near-field radiation patterns in phantom solutions were measured to obtain operature and depth distribution patterns.
