NASA developed and tested a 3D-printed antenna to demonstrate a low-cost capability to communicate science data to Earth. The ...

Abstract: This paper describes a new method for synthesis of a flat-top beam radiation pattern of three-element antenna arrays. Currently, this is the only method that: (1) gives a semi-analytical ...

Do you dream of creating your own clothes or home decor but have a fear of complex patterns and intricate designs holding you back? This helpful list of 38 simple sewing patterns is your magic key to ...

Abstract: This article presents a dual-band dual-mode antenna with omni-directional radiation pattern in the lower band (LB) and reconfigurable pattern in the upper band (UB) for wireless body area ...

"For each p-bit encoding pattern modulated into the programmable metasurface, the metasurface antenna will generate a corresponding radiation pattern," said Cui. "Out of the 2 p possible patterns, 2 p ...

The secondary (false) glideslope generally appears above the primary (real) one. Various radiation patterns from the antenna or other objects combined with the ground reflection of the transmitted ...

The AN/SPY-7 (V)1 antenna will now proceed to final integration with the ASEV combat system at the Production Test Center (PTC-2) in Moorestown in support of full system delivery to Japan. This ...

As reported in the latest issue of Nature Communications, the new platform—dubbed "charge programmed multi-material 3D printing" (CPD)—is a universal system for rapid production of nearly all 3D ...
