Questions of the functional efficiency of medical radiothermograph antennas

A comparative assessment of the designs and characteristics of various antennas used in medical radiothermographs was carried out. The results showed that on the basis of a specified set of parameters, a small-sized printed vibrator antenna with a figure-of-eight emitter, which has an noise immunity level of 35 dB, a measurement depth of 44 mm, and a frequency band of 2. 3 GHz, has the best functional efficiency from the point of view of using these antennas as elements of conformal antenna arrays. © Springer Science+Business Media, LLC, part of Springer Nature 2024.
