최근 개발된 경량 필름형 ESPAR(Electronically Steerable Passive Array Radiator) 안테나의 고조파 왜곡을 실험적으로 조사하였다. 이러한 왜곡은 안테나의 방사 패턴을 제어하기 위해 기생 방사체 요소와 직접 통합되는 버랙터 다이오드의 비선형성으로 인해 발생합니다. 초소형 무반향 상자에 저간섭 프로브를 사용하는 반응성 근거리 측정 기술을 사용하여 실험 시간과 비용을 절감합니다. 역직렬 버랙터 쌍을 도입하고 기존 단일 버랙터와 비교합니다. 결과적으로, 역직렬 버랙터 쌍을 갖춘 ESPAR 안테나는 비선형 왜곡을 현저하게 억제합니다. 특히, 20차 및 12차 고조파는 단일 버랙터형 ESPAR 안테나의 레벨에 비해 각각 약 XNUMXdB 및 XNUMXdB만큼 감소합니다.

Abstract: Harmonic distortions of a recently developed lightweight film-type ESPAR (Electronically Steerable Passive Array Radiator) antenna are investigated experimentally. These distortions arise from the nonlinearity of the varactor diodes that are directly integrated with the parasitic radiator elements to control the antenna's radiation pattern. A reactive-near-field measurement technique that employs low-interference probes in an ultra-small anechoic box is used to reduce experimental time and cost. An anti-series varactor pair is introduced and compared with the conventional single varactor. Consequently, an ESPAR antenna equipped with the anti-series varactor pair exhibits remarkable suppression of nonlinear distortion. In particular, the second- and the third-order harmonic is reduced by approximately 20 dB and 12 dB from the level of a single varactor type ESPAR antenna, respectively.
