How large-area electronics can be adapted to create a gigahertz phased-array antenna. The potential advantages of this approach versus discrete components. The test arrangement used and some test ...

This is the second article of our three-part series on phased array antenna patterns. In Part 1, we introduced the phased array steering concept and looked at the influencers on array gain. In Part 2, ...

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 ...

For some applications single element antennas are unable to meet the gain or radiation pattern requirements. Combining several single antenna elements in an array can be a possible solution. This ...

A radar can be used to locate a buried object. Therefor the radar should operate at low frequencies to be able to penetrate the medium the object is buried in and it should have a high spatial ...

A log-periodic antenna, also known as a log-periodic array or aerial, is a directional and narrow beam antenna that operates over a wide bandwidth. Its advantage is that it exhibits essentially ...

In short: The first antenna has been installed in Western Australia for what will be the world's largest radio telescope. Scientists say the facility will be a "time machine", offering insights into ...

Amazon’s Project Kuiper hasn’t yet said when it’ll start launching satellites or providing broadband internet access from above, but it is sharing details about how customers will get their data. The ...
