Abstract
A circularly polarized antenna device, which is connectable to a wireless terminal measurement apparatus for performing measurements on a device under test (DUT) provided with an antenna on one surface of the DUT, includes a circularly polarized antenna and a holder. The circularly polarized antenna includes a dielectric substrate and a circularly polarized type of antenna element formed on a first surface of the dielectric substrate. The first surface is opposite to the one surface of the DUT. The circularly polarized antenna is spatially coupled to the antenna of the DUT. The holder holds the circularly polarized antenna and the DUT such that the one surface of the DUT and the dielectric substrate are not parallel to each other.
