Researchers developed a low-cost, scalable terahertz amplifier that could be used to make antenna arrays that can steer and focus high-frequency terahertz waves, for applications like high-resolution ...

WASHINGTON — After nearly three years operating in stealth mode, Seattle-based startup Kapta Space emerged on Feb. 21, announcing plans to demonstrate metasurface antenna technology for space-based ...

The best long-slot toasters have greater capacity than standard slot toasters, so you can use them to toast irregularly shaped bread, bagels, sliced muffins, and more. We tested the best long-slot ...

Abstract: A millimeter-wave (mmW) dual-band dual-circularly polarized high-efficiency radial line slot array (RLSA) antenna fed by gap waveguide technology is presented in this paper. By introducing ...

If you want to cut the cord but keep live TV, you need the right antenna to tune into over-the-air broadcasts. Here's what you need to know, along with our top picks. I’ve been PCMag’s home ...

All you need is an antenna to tune into TV stations the old-fashioned way (in high-definition with digital signals, of course). If you want to keep up with local programming or just want some more ...

The revelation of the Jiamusi Large Phased Array Radar (LPAR) station, located in the northeastern Chinese province of Heilongjiang, came after the United States test-launched an unarmed but ...

The best TV antennas are no longer the bunny ear-style TV toppers of yesteryear; they are diminutive but powerful with tons of variations depending on the range and design you’re after.

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 ...

Abstract: This work proposes an electrically tunable reconfigurable antenna array with wideband ... between a patch mode and a slot mode, achieving a wideband reflection phase difference of 180°±37°.
