Antenna testing

MIMO and active beamforming system design and test

Antennas are receiving more and more attention in the system level design due to MIMO and active beamforming. Beamforming is a standard feature in radar applications. And with 5G and microwave frequencies in mobile communications, it will also become an essential feature in this area. Especially at millimeterwave frequencies, it is necessary to overcome the free field attenuation at higher frequencies.

Rohde & Schwarz offers a full range of solutions for chambers and shield boxes in almost any physical size, supporting far field and near field testing and including a software solution for near field to far field transformation.

Beamforming antenna characterization

Beamforming antenna characterization

Radar, satellite communications and 5G NR use AAS with phased array antennas for beamforming. Increasing integration enables compact and cost-efficient AAS.

While discrete components like phase shifters, switches and amplifiers are tested conducted, highly integrated frontends with antenna-in-package (AiP) and system level tests require over-the-air (OTA) testing.

Antenna performance verification

Antenna performance verification

Antennas translate electric signals into RF waves, enabling wireless communication. There are many different antenna forms based on the frequency and application. To ensure no loss and proper operation, parameters such as matching, intermodulation and performance impact need to be verified.
