In this paper we summarize measured receive antenna performance for a commercially available 32-element phased array demonstrator. The demonstrator is configured for hybrid beamforming with eight elements per subarray and four digital channels. The test setup and calibration steps are explained sequentially along with the measured calibration accuracy achieved. Three-dimensional radiation patterns of the antenna array are shown for various electronically steered beam positions including amplitude tapering.
Recent trends and developments, such as 5G deployment, massive MIMO and beamforming, automotive radar, and space applications, are shaping the field of RF communications of the 21st century, particularly in the context of millimeter waves. In this article, the concept of a conventional surface mount planar Wilkinson power splitter is revisited and examined at frequencies above 20 GHz.
Wilkinson Power Divider’s are widely used in many RF and microwave communication systems, including those with multiple channels or complex feed networks. Learn more about how Wilkinson Power Dividers work and how they play a crucial role in overall device performance.
A technical collaboration between Teledyne e2v, France, and Fraunhofer IIS, Germany, recently evaluated the performance of a four-channel digitally steered 2.4 GHz planar antenna system. In this, a pair of state-of-the-art, gigahertz capable, digitalto-analog converters (EV12DD700) featuring a slew of novel, on-chip digital beamforming controls delivered digital beam steering control. The aim - to gain further validation of Teledyne e2V’s advance towards microwave RF softwarization.

Characterizing Radar Cross Section (RCS) is no easy task. Most ranges use low back-scattering pylons that require a low RCS target to hide the top edge of the pylon to measure the effect of the support. This article explores the idea of using a numerical technique as an effective alternative.
Segmentation is a powerful tool in extending the capabilities of otherwise workpiece size or workspace limited Additive Manufacturing technologies, and can enable the fabrication of complex dielectric structures. This is especially critical for highly intricate dielectric structures, such as metastructures, and Luneburg/GRIN RF lenses greater than 4.5” in diameter.
The proposed capability enhancements from 4G long-term evolution (LTE) to 5G new radio (5G NR) were a massive leap designed to boost mobile telecommunications applications and enable many more. Aside from significantly boosting all major performance metrics, the 4G to 5G transition also heralds a more flexible and capable radio architecture with additional millimeter-wave frequency spectrum on top of legacy 4G LTE-Advanced (LTE-A) and new sub-6 GHz frequency bands.
With its small footprint, the R&S®ATS1000 antenna test system is the ideal direct far-field OTA system to test phased array antennas. The system tests and optimizes the radiation characteristics of any modules using the AiP technology from 18 GHz to 87 GHz. Register and learn more in our paper.
