Abstract
Systems and methods for antenna pattern measurement are provided. One system includes a plurality of wireless sensors arranged in an array, wherein the wireless sensors are configured to be powered by radio-frequency (RF) signals at different power levels. The system also may include a controller configured to wirelessly transmit the RF signals at different power levels and measure responses from the wireless sensors at the different power levels. The system may further include a processor configured to calculate a radiation pattern of an antenna under test using the measured responses.
