摘要：
This paper applies an existing method for estimating the system gain and noise figure of active integrated antennas to W-band frequencies. The method uses a reverberation chamber as a wireless noise source, where the ENR can be tuned. Measurements, including different calibration steps, are performed to obtain the noise figure and system gain of a horn antenna connected to a low-noise amplifier as a proof of concept for measuring an integrated antenna. The preliminary measured results are within 1.0 dB of the datasheet value for part of the measured frequency span. Limits of this method are demonstrated through the measurement campaign and recommendations for improvement are provided.
