Abstract
(EN)
The present invention relates to an antenna performance tester comprising: a horizontal rotor (200) rotatable about a shaft part (110) to which a DUT holder (300) is detachably coupled; and a vertical rotor (500) to which a reference antenna holder (400) is detachably fixed and which is spaced apart from the side surface of the DUT holder (300), is installed perpendicular to the horizontal rotor (200), and is rotatable about a virtual center point lying at the center thereof. The present invention is advantageous in that: a reference antenna that is at a constant distance from a device under test can measure an RF while performing transmission and reception with the device under test in all directions, and can be extended or replaced depending on the frequency to be measured; and the influence of reflected waves on the RF measurement is minimized and thus antenna performance can be simply tested in an anechoic chamber or even in a semi-anechoic chamber.

La présente invention concerne un testeur de performances d'antenne comprenant : un rotor horizontal (200) pouvant tourner autour d'une partie d'arbre (110) à laquelle un support de dispositif sous test (DUT) (300) est accouplé de manière amovible ; et un rotor vertical (500) auquel un support d'antenne de référence (400) est fixé de manière amovible et qui est espacé de la surface latérale du support de DUT (300), est installé perpendiculairement au rotor horizontal (200), et peut tourner autour d'un point central virtuel situé au centre de celui-ci. La présente invention est avantageuse en ce que : une antenne de référence qui est à une distance constante d'un dispositif sous test peut mesurer une RF tout en effectuant une transmission et une réception avec le dispositif sous test dans toutes les directions, et peut être étendue ou remplacée en fonction de la fréquence à mesurer ; et l'influence des ondes réfléchies sur la mesure RF est minimisée et, ainsi, les performances d'antenne peuvent être simplement testées dans une chambre anéchoïque ou même dans une chambre semi-anéchoïque.

본 발명은 안테나 성능 시험장치에 관한 것으로, DUT거치대(300)가 착탈 가능하게 결합되는 축부(110)를 중심점으로 회전 가능한 수평 회전체(200)와, 기준안테나거치대(400)가 착탈 가능하게 고정되며 DUT거치대(300)의 측면에서 이격되고 수평 회전체(200)와 수직하게 설치되며 중앙 가상의 중심점을 기준으로 하여 회전 가능한 수직 회전체(500)를 포함한다. 본 발명은 피시험장치에서 일정거리에 있는 모든 방향에서 기준안테나가 피시험장치와 송수신하면서 RF를 측정할 수 있으며, 측정하고자 하는 주파수에 따라 확장 및 교체가 가능하고, RF 측정시 반사파 영향이 최소화되므로 무반사실이나 반무반사실에서도 간단하게 안테나 성능 검사가 가능한 이점이 있다.
