Antenna test systems and methods are disclosed. An antenna test system as disclosed herein can include an X-Y isolation structure that defines a plurality of unit cells, a plurality of coupling elements, with at least one coupling element within each unit cell, and a Z isolation structure. The size and general configuration of the unit cells are selected to allow the individual antenna elements of an array antenna to be placed within a unit cell. Each unit cell thus isolates an antenna element. The disclosed methods include passing energy between antenna elements and corresponding unit cells to characterize the performance of the antenna. An antenna test system as disclosed herein enables the costs associated with testing phased array antenna systems, including but not limited to antennas used in 5G communication systems, to be reduced as compared to prior techniques.

Systems and methods for automated testing and calibration of phased array antenna systems

An antenna system circuit board stack with feed vias and with non-feed vias is disclosed. An antenna system circuit board stack as disclosed herein can include a plurality of patches or radiating elements formed on a common plane comprising a first surface of a circuit board. Each radiating element is electrically connected to one or more feed vias. In addition non-feed vias extend through, but are electrically isolated from, the radiating elements. An antenna system as disclosed herein enables the costs associated with multiple beam antenna systems, including but not limited to 5G communication systems, to be reduced as compared to alternative techniques.
