Antenna Array Testing – Conducted and Over the Air: The Way to 5G

5G networks will need to offer more capacity and flexibility while lowering the operational expenses of the system. Two new technologies can simultaneously address both the increase in capacity and the increase in energy efficiency: Virtualization & Massive MIMO. This white paper provides an overview of test solutions addressing current and future requirements for antenna… Read more »

LTE and Bluetooth® in-device coexistence with WLAN

This application note employs preliminary theoretical analysis and demonstrates how the problems of in-device coexistence can be measured. Exemplary, the effects of LTE and Bluetooth® traffic on the WLAN performance of a commercially available smartphone are examined. These examples will also enable the reader to design tests for complementary scenarios.

Characterizing Active Phased Array Antennas

Designing and implementing an active phased array antenna requires precise characterization of individual components and the integrated performance of the array. To ensure an accurate test of the intended adaptive nature of the active phased array antenna, the embedded algorithms need to be tested as well. This application note aims to explain test procedures and… Read more »

Millimeter-Wave Beamforming: Antenna Arrays & Characterization

Millimeter-wave bands are of increasing interest for the satellite industry and under discussion as potential 5G bands. Antennas for 5G applications make use of the shorter element sizes at these high frequencies to incorporate a larger count of radiating elements. These antenna arrays are essential for beamforming operations that play an important part in next… Read more »
