Abstract
A quadrant-partitioned array architecture and measurement sequence supporting mutual-coupling based calibration. The architecture includes an array of radiating elements grouped into quadrants, with a quadrant feed network and an intra-quadrant feed network connected between a transmitter/receiver and the radiating elements. The architecture includes test signal switches which provide access for quadrant testing functions, allowing a test signal to be injected into one quadrant while making measurements of the received signal in an adjacent quadrant. Mutual coupling based module-to-module RF measurements are performed to phase up the array.
