Abstract

Microwave radiometry, as a non-invasive technique which doesn't pierce inside human and can measure the temperature, is to diagnose early the disease or abnormality by measuring the temperature inside human. In this paper, as an antenna for measuring human radiometric signals, we simulated and measured a dipole-type antenna with circular loops. As a measured result has a ultra wideband characteristic of $130%(0.8\sim3.8GHz)\;for\;511\leq-10dB$, it is considered to be suitable to detect the position and size of human tissue having various diseases.

초고주파 방사파 측정(microwave radiometry) 기술은 인체내부를 뚫지 않고 인체내부의 온도를 측정할 수 있는 기술로서 인체 내부의 질병이나 비정상을 조기에 진단할 수 있는 기술이다. 본 논문에서는 인체 방사파 신호를 측정하는 안테나로서 원형루프를 가진 다이폴형 안테나를 시뮬레이션하고 측정했다. 측정 결과는 $S11\leq-10dB$에 대해 $130%(0.8\sim3.8GHz)$의 초광대역 특성을 가짐으로써 다양한 질병을 가지는 인체조직의 위치와 크기를 검출하는데 적합하다고 할 수 있다.
