When we used the WR-15’s internal FM antenna, it picked up 21 of the 45 FM radio stations available in the Albany, New York, area at the time of our testing. (For reference, the best performance ...

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 ...

Abstract: A circular polarization (CP) folded reflectarray antenna is proposed at the 30 GHz band. A five-layered circular polarization selective metasurface (CPSM) is introduced to realize the path ...

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 ...

Our intervention was assessed by researchers at Stanford studying ways to reduce polarization as part of a megastudy involving surveys with about 32,000 people. It was evaluated along with 24 ...

The polarization mode of the antenna adopting the graphene-based current amplitude control method can be tuned between left-hand circular polarization (LHCP) and linear polarization (LP) continuously ...

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 ...
