Over-the-air (OTA) performance evaluation for wireless devices require electromagnetic field measurements in the far-field (FF). This is typically achieved by using one or multiple test probes to scan a sphere encompassing the device under test (DUT)

Total radiated power (TRP) is a key performance metric in over-the-air (OTA) testing of wireless devices. The TRP is evaluated by integration of the power density over a surface enclosing the device under test (DUT). In principle, this total power fl

Two novel decoupling and matching networks (DMNs) in microstrip technology for three-element uniform circular arrays (UCAs) are investigated and compared to a more conventional DMN approach with simple neutralization lines. The array elements are coa
