As the demand for high-speed wireless communication grows, millimeter-wave frequencies, such as the 27 GHz band, have become increasingly important for 5G and beyond. However, operating at these ...

NASA developed and tested a 3D-printed antenna to demonstrate a low-cost capability to communicate science data to Earth. The antenna, tested in flight using an atmospheric weather balloon, could open ...

Here’s how it works. The best TV antennas are a critical element of any living room. I couldn't live without my TV antenna. It's as important to me as any streaming service because it allows me ...

Jason Adcock is the Principal of Adcock Prestige. He has been recognised by his peers for his energetic, dynamic approach to the Brisbane Prestige Property market and applauded for his innovative ...

Most readers will be aware that a good way to extend WiFi range is to use a better antenna for those 2.4 GHz signals, but at the same time such high frequency hijinks have something of a ...

Cellular signal boosters use big antennas to improve coverage in your home or car. These are the top signal boosters for apartments, houses, and vehicles. I’m one of PCMag’s mobile analysts.

Abstract: Localizing near-field sources considering practical arrays is a recent challenging topic for next generation wireless communication systems. Practical antenna array apertures with closely ...

Abstract: We present a numerical method for the analysis of mutual coupling effects in large, dense and irregular arrays with identical antennas. Building on the Method of Moments (MoM), our technique ...

Abstract: Two beam broadening methods for active electronically scanned array (AESA) antennas with uniform amplitude excitation are proposed and compared: phase tapering optimization (PTO) and a novel ...

Jimmy Adcock, age 85, passed away January 17, 2025. He was a lifelong resident of Rutherford County and a retired mechanic. Jimmy was preceded in death by his parents, Clyde Felix Adcock and Bessie ...

Abstract: A class of antennas that utilizes arrays of elementary antennas as reflecting surfaces has been investigated. An antenna of this type is here called a Reflectarray. It has been found that ...

I had once built a two element vertical array with one half of wavelength separation between the elements. It was in mid 90s when we were active as RZ9AZA. We were either feeding the elements in phase ...
