Abstract

See full text

Disclosed is herein an antenna performance tester including: 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 a side surface of the DUT holder 300, is installed perpendicular to the horizontal rotor 200, and is rotatable about a virtual central point lying at the center. The antenna performance tester is advantageous in that: a reference antenna measures an RF while performing transmission and reception with respect to a DUT in all directions at a constant distance from the DUT; extension and replacement are possible depending on a frequency to be measured; and an influence of reflected waves is minimized at RF measurement, antenna performance can be simply tested in an anechoic chamber or even in a semi-anechoic chamber.
