This paper consists of two parts. The first part presents a review of the recent development in broadband circularly polarized filtering antennas. The second part presents a novel design of broadband ...

This article introduces a low-cost, easy-to-manufacture, dual polarization reconfigurable reflectarray antenna based on liquid crystal (LC) that operates at W-band. The antenna is electrically large ...

Wearable visible light communication systems face fundamental limitations in dense multi-input multioutput configurations due to signal crosstalk between channels. Here, we demonstrate shear-aligned ...

Antennas installed at 18 U.S. high schools detected bursts of radio activity that can precede solar disturbances capable of disrupting satellites and power grids on Earth. The observations helped ...

A misaligned antenna could be the difference between mobile signal or not, that’s why Vodafone is using satellites to guarantee positioning. Vodafone will begin rolling out satellite-guided sensors ...

Space ‘Bunch of SCARS’: Space Force’s Hammett speeds phased array antenna integration " [T]his capability is so important to where we're headed in the next couple of years, with having the ...
