Abstract: A dual-stopband rectangular waveguide slot array antenna is presented in this article. First, a rectangular filtering waveguide with dual stopbands is realized by periodically loading a row ...

Abstract: In this paper, a new topology for rectangular waveguide bandpass and low-pass filters is presented. A simple, accurate, and robust design technique for these novel meandered waveguide ...

High-powered satellites use electromagnetic waveguides to deliver energy from one component to another. Typically, they are made of heavy, inflexible metal tubes with an even heavier flange on either ...

Traditional wired systems have their own limitations in industrial settings. For example, conductor bars are restricted to analog signals, festoons and cable reels are limited to 330 feet for Ethernet ...

We may receive a commission on purchases made from links. Even Realities has turned up at CES 2025 in Las Vegas to show off its smart glasses, the G1, which have been out for a few months now. The ...

5G base stations rely on phased arrays to steer signals and increase data rates. Beam steering circuits, however, consume power. Using waveguides could reduce energy consumption in base stations.

One of the most important components of satellites that enable telecommunication is the waveguide, which is a metal tube for guiding radio waves. It is also one of the heaviest payloads satellites ...

Researchers fabricated 20mm length waveguides made of the superconducting metal niobium (right). It shows improved conductivity compared with normal metal materials such as a gold-plated tellurium ...
