We all know that space has no air, and without air or water, sound waves cannot travel. So, how do astronauts communicate ...

A broadband horizontally polarized omnidirectional antenna with stable radiation patterns for base station applications is proposed in this paper. The stable omnidirectional patterns are achieved by ...

High-power radiations from active antenna arrays may result in strong reflected power to cause RF device breakdown by the strong interelement mutual coupling. An excitation weighting synthesis of ...

The rollout of 5G technology has promised faster internet speeds and more reliable connections, but it has also raised ...

Learn how laser tech, 3D printing & bio-materials are reshaping off-Earth construction for lunar & Martian habitats.

Satellite observation of the imbalance between incoming and outgoing radiation in the atmosphere, which causes global warming ...
