Patent ID: 10419135

Abstract:
The present invention provides an over the air, OTA, power sensor (1, 20, 50) for measuring power of a wireless signal (2, 21) with at least two different polarizations, the OTA power sensor (1, 20, 50) comprising a first power sensor (3, 4, 22, 23, 51, 52) for every polarization, every power sensor comprising a signal detector (5, 6, 25, 26, 27) for detecting the wireless signal (2, 21), wherein the signal detectors (5, 6, 25, 26, 27) are single polarized and wherein the polarization planes (7, 8, 28-30) of the signal detectors (5, 6, 25, 26, 27) are arranged at an angle of more than zero degree to each other and wherein the main radiation vectors (9, 10, 31-33) of the signal detectors (5, 6, 25, 26, 27) are parallel to each other, and the first power sensors (3, 4, 22, 23, 51, 52) each comprising a power measurement device (11, 12, 43-45), which is configured to measure the power of the detected wireless signal (2, 21) and output a respective measurement signal (13, 14, 46-48, 55-58). Further, the present patent application provides a respective method.
