Abstract

In this paper, the SIW(Substrate Integrated Waveguide)-based feeding antenna for the application of SDR(Software Defined Radar) is designed and manufactured. It is usually well-known that SIWs are easily integrated on PCB and have low transmission loss toward high powered input signal. Also, it is recommended that SIWs are strongly immunized to Electromagnetic Interferences(EMI). In particular, the manufactured antennas are loaded on the USRP(Universal Software Radio Peripheral) platform and employed to detect target RCS as an experiment in this paper. The operating frequency of the proposed antenna is in ISM(Industrial, Scientific and Medical) band(2.4~2.48 GHz) and the measured gain is over 8 dBi at 2.44 GHz.

본 논문에서는 SIW(Substrate Integrated Waveguide) 구조를 갖는 SDR(Software Defined Radar)용 안테나를 설계하고 제작하였다. SIW 구조는 쉬운 집적화로 인하여 일반 PCB 상에 구현이 가능하고, 기존의 구형 도파관과 같이 높은 전력의 입력 신호에 대하여 낮은 전송손실을 가지는 특성이 있다. 또한, 전자기 간섭에 대하여 강한 내성을 갖는 장점이 있다. 특히 본 논문에서는 제작한 SIW 안테나를 가지고 USRP(Universal Software Radio Peripheral) 플랫폼에 탑재하여 목표물 RCS(Radar Cross Section)탐지 실험을 진행하였다. 제안된 안테나는 ISM(Industrial, Scientific and Medical) 대역(2.4~2.48 GHz)에서 동작하며, 이득 특성은 8 dBi 이상을 보인다.
