NASA's Deep Space Network, an array of giant radio antennas, allows agency missions to track, send commands to, and receive scientific data from spacecraft venturing to the moon and beyond.

The best indoor TV antennas let you receive free over-the-air broadcast TV channels without having to install a large outdoor antenna on the roof of your home. You’ll find that the main ...

Argus II users undergo surgery to implant an electrode array inside the eye on the surface of the retina and affix a small electronics case (like a metal button) and an antenna to the outer ...

The angle of the antennas can make a difference, too. If you can, try staggering them at 45-degree intervals: one straight up, the next diagonal, the next straight back. It might take some ...

Abstract: A new class of via-less dual-band wide stopband filtering antenna is proposed. The proposed topology is based on a stacked patch antenna structure which is excited using a proximity coupled ...

Abstract: It is well known that the phenomenon of radiation from line-source antennas is very similar to that of the diffraction of light from narrow apertures. Unlike the optical situation, however, ...
