1. A radio frequency antenna measurement system comprising:
a stage supporting an on-chip radio frequency antenna configured to be measured;
a feed probe configured to feed an input radio frequency signal to the radio frequency antenna;
a receiving antenna configured to receive a radiated radio wave from the radio frequency antenna; and
a power sensor configured to measure a radiation characteristic of the radio frequency antenna in response to a reception signal output from the receiving antenna,
wherein the receiving antenna includes a waveguide in which a connector for outputting the reception signal to the power sensor is integrally formed at a rear end.
