Abstract

In this paper, a low temperature co-fired ceramic cavity backed antenna in order to improve the performances of radiation and bandwidth for the antenna with high relative dielectric constant is proposed. Low temperature co-fired ceramic cavity consisted of several ground planes with closely spaced metallic vias connected. It is shown that the size of a low temperature co-fired ceramic cavity has the effects on the performances of radiation and bandwidth for the antenna. The proposed 2x4 low temperature co-fired ceramic cavity backed antenna is $10{\times}20\;mm^2$ in size. Measured results show antenna gain of $11.8{\sim}14.1\;dBi$ and bandwidth of 13 %(7.9 GHz) in the $57{\sim}64\;GHz$ band.

본 논문에서는 상대 유전율이 큰 low temperature co-fired ceramic 기판을 이용한 안테나의 복사 성능을 높이고, 대역폭을 개선하기 위하여 low temperature co-fired ceramic cavity backed 안테나가 제안된다. Low temperature co-fired ceramic cavity는 각 층의 접지면을 다수의 비어로 연결하여 만들어진다. 그리고, cavity의 크기가 안테나의 복사 성능과 대역폭 성능에 미치는 영향을 보여준다. 제안된 $2{\times}4$ low temperature co-fired ceramic cavity backed 안테나의 크기는 $10{\times}20\;mm^2$이며, $57{\sim}64\;GHz$ 대역에서 이득 $11.8{\sim}14.1\;dBi$, 대역폭 13 %(7.9 GHz)을 가진다. 측정 결과는 시뮬레이션 결과와 매우 잘 일치함을 보여준다.
