Utilizing slot cavity geometry, the RD series antenna is capable of wideband, low VSWR transmission for up to 20 channels. This capability makes it possible for stations to utilize a single antenna for Analog and DTV channel allocation and relocation assignments which fall within 20 … US4547779A - Annular slot antenna - Google Patents A microstrip annular antenna structure is formed by four quarter-wavelength microstrip radiator patches arranged in a quadrant formation and having outwardly directed adjacent radiating apertures which together provide a composite annular radiating slot extending about 360° of azimuth. All such radiators are fed in-phase by a single centrally located feedpoint and equal length microstrip US Patent for Cavity slot antenna Patent (Patent In one embodiment, the present invention provides an antenna array for transmitting one or more beams in a communication system. The antenna includes a cavity slot antenna array that is adapted to be operatively connected to a beam forming module (e.g., via a plurality of signal feed lines that are connected to radiating signal probes). The antenna array has one or more cavity slot columns US Patent for Dual slot microstrip antenna device Patent
Abstract: Single fed low profile cavity backed crossed slot antennas for dual frequency dual linear polarization and circular polarization applications are first presented in this paper. By employing the substrate integrated waveguide (SIW) technique in the antenna designs, the low profile backed cavity structure can be realized by using only a single layer of low cost printed circuit board ...
