Evaluation of a Random Line-of-Sight Over-the-Air Measurement Setup at 28 GHz

Over-the-air (OTA) measurement techniques have, and will continue to a key role in evaluating the performance of modern antennas wireless devices. The new random line-of-sight (random-LOS) setup offers evaluation OTA different types devices, for example, car small devices random-LOS environment. A plane wave is synthesized test zone setup, where far-field radio base station can be emulated. We present measurements simulations employing reflector antenna, with dual-polarized linear array feed, operating at 28 GHz band. An analysis power phase-field distributions cylinder circular presented. computed standard deviation (STD) distribution approximately 1dB within zone, diameter 0.3m. STD phase, same less than 15°. radiation patterns horn antenna have been measured shown good agreement theoretical values.
