안테나 방사 패턴 측정
안테나 설계에서 최종 제품에 통합하기 전과 후에 안테나를 실제로 테스트하고 측정하면 안테나 성능이 최적인지 검증할 수 있는 가장 정확한 수단이 됩니다. 안테나 방사 패턴 측정은 테스트 대상 안테나로 송수신되는 전파 방향의 각도 강도를 이해하는 데 핵심적인 역할을 합니다.
안테나 방사 패턴 시각화, 평가, 조정, 검증
안테나특성화의초기단계는안테나방사패턴을측정하여안테나에서에너지가어느방향으로얼마나잘방사되는지확인하는것으로시작됩니다. 결과는테스트중인안테나의상대적인크기와위상을나타냅니다. 이득, 효율, 편광과같은 S-파라미터는측정을통해 2D 또는 3D 플롯상방사패턴을시각화하여정의됩니다.
MVG는방사패턴및 S-파라미터결정부터 OTA 및실제기능테스트에이르기까지광범위한안테나테스트요구사항에대해완벽한테스트및측정솔루션을제공합니다. MVG Near-field, Far-field 및 Compact range 안테나측정시스템은몇분안에정확한구형, 원통형또는평면좌표상측정패턴결과를제공합니다.
