In Part 1, we introduced the phased array concept, beam steering and array gain. In Part 2, we presented the concept of grating lobes and beam squint. In this section, we begin with a discussion of ...

Phased array technology is far from new. Phased-array antennas have been used for decades in a variety of military applications. Now, however, their use in 5G systems in the Band 2 frequency range is ...

Advances in semiconductor technology have enabled the proliferation of phased array antenna with active electronically scanned antenna (AESA) advancing in satcom on-the-move and 5G communications.

Peter Delos, Technical Lead, Bob Broughton, Director of Engineering and Jon Kraft, Senior Staff Field Applications Engineer, all with Analog Devices. With the proliferation of digital phased arrays in ...

A significant performance element in communication and radar systems, as well as wireless devices, is the antenna, which may be defined as a transducer between a guided electromagnetic (EM) wave ...

An industry expert offers some suggestions for dealing with the challenges of testing today's high-frequency antennas. A common solution to EMC/EMI test requirements is the rectangular anechoic ...

Phased array antenna systems are at the cusp of ubiquity. We now see Multiple-Input Multiple-Output (MIMO) antenna systems on WiFi routers. Soon phased array weather radar systems will help to predict ...

When it comes to actual antennas in the real world, much of our knowledge is empirical. We know very broadly theories that explain how a point charge radiates (Maxwell’s equations), the need for ...
