Abstract
The results of designing a printed ultra-wideband antenna intended for use as a part of a multichannel microwave radiometer are presented. The design of a ring-shaped antenna with a built-in infrared sensor for measuring skin temperature is proposed. The results of numerical simulation of the electromagnetic field of the antenna in tissues of a biological object are presented. The results of calculating the voltage standing wave ratio, measurement depth of the antenna, the resolution, and the distribution of radiation power over the tissue volume under study are presented.
