    摘要: In the antenna device, a first insulating plate, a capacitive coupling portion of a tuning plate, a radio wave absorber, a grounding portion of the tuning plate folded back to the back side of the radio wave absorber, and a tuning coated plate provided with a metallic plated film formed on the surface thereof are sequentially stacked below an antenna element having a shape obtained by removing an arched portion from a copper circular plate. Power is supplied from a center conductor of a semi-rigid signal input member to a power feeding unit of the antenna element. An external conductor is held between the upper and lower conductive cushions. A grounding plate is conductive with the external conductor, to ground the grounding portion and the tuning coated plate.

    摘要: The present invention performs characteristic tests on a communication device with a compact and simple configuration. A testing device 1 that performs characteristic tests in a near field on a communication antenna 250 of a communication device 240 includes a tray body 220 that supports the communication device in a test space S as an anechoic chamber, and a coupler support frame 520 that supports coupler antennas transmitting and receiving radio waves to/from the communication antenna 250. The coupler support frame can form inner-periphery coupler antenna arrays 300A and 300B each including a plurality of coupler antennas 300 arranged at least in a row along a curve extending along an inner peripheral surface composed of side surface S1 and S2, an upper surface S3, and a lower surface S4, and a rear coupler antenna array 300C including a plurality of coupler antennas 300 arranged at least in a row in an upper-lower direction along a curve extending along a rear surface S5.
