Using heat-activated nitinol metal, researchers have devised a reversible, shape-shifting, conical spiral antenna that needs ...

The overall gain of an antenna (not including the radiation pattern) is determined by two, somewhat independent, factors. The first is the match between the antenna and its feed network—the antenna ...

Abstract: This work presents a novel biconical antenna producing stable gain and radiation patterns in an ultrawide operating bandwidth. Conventional biconical antennas have ultrawide bandwidths, but ...

Abstract: High-resolution wide swath (HRWS) synthetic aperture radar (SAR) systems are normally designed to have identical antenna patterns in each receive channel. Nevertheless, due to different ...
