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 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 ...

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 ...

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.

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 ...

THE ANTENNA IS A CRITICAL COMPONENT OF ANY GNSS RECEIVING EQUIPMENT. It must be carefully designed for the frequencies and structures of the signals to be acquired and tracked. Important antenna ...

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 ...

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 ...
