Title (EN) MULTI-ANTENNA TRANSMISSION AND RECEPTION DEVICE
(FR) DISPOSITIF D'ÉMISSION ET DE RÉCEPTION À ANTENNES MULTIPLES
(KO) 다중 안테나 송신 및 수신 장치
Abstract: front page image
(EN)A multi-antenna transmission device of the present invention can comprise: an RF resonator for generating a reference signal in a carrier frequency; a power amplifier for amplifying the generated reference signal to a signal of a preset magnitude; N number of switches for individually adjusting the magnitude of a transmission signal for each channel to be wirelessly transmitted, on the basis of the amplified reference signal for each channel; N number of inverters for individually determining a sign of the magnitude-adjusted transmission signal for each channel; and a transmission antenna integrated structure in which N number of antennas having different patterns and polarization characteristics individually and wirelessly transmit the determined transmission signal for each channel in different radiation patterns.
(FR)La présente invention concerne un dispositif d'émission à antennes multiples pouvant comporter: un résonateur à RF servant à générer un signal de référence dans une fréquence porteuse; un amplificateur de puissance servant à amplifier le signal de référence généré pour donner un signal d'une amplitude prédéfinie; un nombre N de commutateurs servant à régler individuellement l'amplitude d'un signal d'émission pour chaque canal à émettre sans fil, sur la base du signal de référence amplifié pour chaque canal; un nombre N d'onduleurs servant à déterminer individuellement un signe du signal d'émission réglé en amplitude pour chaque canal; et une structure intégrée d'antennes d'émission dans laquelle un nombre N d'antennes présentant des diagrammes et des caractéristiques de polarisation différents émettent individuellement et sans fil le signal d'émission déterminé pour chaque canal dans des diagrammes de rayonnement différents.
(KO)본 발명의 다중 안테나 송신 장치는, 반송 주파수에서의 기준신호를 발생하는 RF 공진기와, 발생된 상기 기준신호를 기 설정된 크기의 신호로 증폭하는 전력 증폭기와, 증폭된 각 채널별의 기준신호에 기반하여 무선 송출하고자 하는 각 채널별 송신신호의 크기를 각각 조절하는 N개의 스위치와, 크기가 조절된 각 채널별 송신신호의 부호를 각각 결정하는 N개의 인버터와, 서로 다른 패턴 및 편파 특성을 갖는 N개의 안테나가 결정된 각 채널별의 송신신호를 서로 다른 방사 패턴으로 각각 무선 송출하는 송신 안테나 집적 구조를 포함할 수 있다.
