An impedance matching structure for a RF MEMS switch having at least one closeable RF contact in an RF line, the impedance matching structure comprising a protuberance in the RF line immediately adjacent the RF contact that forms one … US5654723A - Contrawound antenna - Google Patents A typical vertical whip antenna (a monopole) possesses an omnidirectional vertically polarized pattern, and such an antenna can be comparatively small at high frequencies, such as UHF. US4899162A - Omnidirectional cylindrical antenna - Google… The antenna can be energized by a three-layer printed circuit line. It can be made up by an array of doublets folded into sheets.
A design for linearly polarized radial line slot antenna (RLSA) is proposed. A novel slot arraignment is presented which couples to the rotationally symmetric guided waves to produce a uniform aperture distribution with linear polarization. Basic characteristics were measured in the 12-GHz band on a model antenna.
