Novel Probe Array Design for Fast and Cost-Effective Array Antenna Verification in Production Environments

Steerable antenna arrays are an increasingly vital part of modern communications and radar applications, but their production in large quantities poses challenges for manufacturers. These antenna arrays are constructed from multiple single-element antennas, which are connected to one or multiple beamforming monolithic microwave integrated circuits. The number of antenna elements of electronically steerable antennas (ESAs) can range from 2 × 2 up to 128 × 128 elements.
