Problems solved by technology

The horn antenna has a structure with a very large wavelength relative to the frequency band to be measured, so there is a disadvantage that accurate measurement cannot be performed unless it is separated from the object to be measured, that is, the communication device, for example, by 1m or more.
However, when the distance between the communication equipment and the horn antenna is large, the space loss becomes large, and there is a problem that the emission level of the spurious component cannot be measured

Abstract

The present invention performs, with a compact and simple configuration, characteristic test on a communication device. A testing device 1, which tests characteristics of a communication antenna 250 of a communication device 240 in a near field, is provided with: a tray body 220 that supports the communication device in a test space S serving as a radio wave darkroom; and a coupler support frame 520 that supports a coupler antenna for transmitting / receiving a radio wave to / from the communication antenna 250. The coupler support frame can form: inner-peripheral coupler antenna arrays 300A, 300B which comprise a plurality of coupler antennas 300 arranged at least in a row along a curve extending along an inner peripheral surface formed from the lateral surfaces S1, S2, the upper surface S3, and the lower surface S4; and a rear coupler antenna array 300C which comprises a plurality of coupler antennas 300 arranged in a row at least vertically along a curve extending along a rear surface S5.

Description

technical field [0001] The present invention relates to a test device for communication equipment, which performs a characteristic test of a communication antenna for a microwave band included in a communication device such as a smart phone, and particularly relates to a test device for performing a characteristic test of a fixedly arranged communication device in a near field . Background technique [0002] Portable terminals such as smartphones, base stations, or various wireless modules (hereinafter collectively referred to as "communication equipment") must comply with the technical standards stipulated in the Radio Wave Act. For each communication equipment, a characteristic test is performed to test whether it meets the technical standards before starting operation. The characteristic test is carried out in an anechoic chamber that blocks (or attenuates) the intrusion of radio waves from the outside and the leakage of radio waves to the outside, and forms a space insid...
