Abstract

In this paper, we designed a 24.4GHz 2-channel TX and 4-channel RX patch array antenna mounted on a short-range vehicle radar system to simultaneously measure the range and speed of a single object within a single measurement cycle. The antenna was designed and fabricated using Rogers' RO4350B(εr=3.48, 0.5T) board. Through measurement, it was confirmed that the design specifications of antenna gain (> 10dBi or more) and radiation pattern (Elevation HPBW > 10deg.) were satisfied at 24.4 GHz frequency.

본 논문에서는 단일 측정 사이클 내에서 단일 물체의 범위와 속도를 동시에 측정하기 위한 근거리 차량용 레이더 시스템에 장착되는 24.4GHz 2채널 송신 및 4채널 수신 패치 배열 안테나를 Rogers사의 RO4350B(εr=3.48, 0.5T) 기판을 사용하여 설계·제작하였다. 측정을 통해 24.4GHz 주파수에서 안테나 이득( > 10dBi 이상) 및 복사패턴(Elevation HPBW > 10deg.)의 설계 사양을 만족하는 것을 확인하였다.
