  • Patent number: 12265110
    Abstract: A radio frequency antenna measurement system (10) of the present invention includes a receiving antenna (14) that receives a radiated radio wave from an on-chip radio frequency antenna (AUT). The receiving antenna (14) includes a waveguide (14A) in which a connector (14B) for outputting a reception signal to the power sensor (15) is integrally formed at a rear end. Accordingly, in a state where a microscope (MS) necessary for position adjustment of a feed probe (12) is installed, it is possible to construct a reception system that receives the radiated radio wave from the AUT and measures a radiation characteristic on a stage (11), and to measure the radiation characteristic such as a gain and radiation pattern of the AUT with high accuracy.
