Wideband Dual-Frequency Dual-Polarized Dipole-Like Antenna

An array of antennas comprising a plurality of printed antennas, each antenna being supported by a dielectric substrate and comprising first and second dipoles each having a T-shaped conductive element including a stem and two radiating arms separated by a coupling slot made in said stem, and a feeder, the stem and the arms of the second dipole ... EP2904663A1 - Dual band interleaved phased array antenna ... The height of crossed-dipoles antenna elements can be reduced by including an additional bend/segment in the feed-line and/or tuning-stub of the antenna dipole having the upper slot. The extra bend allows the crossed-dipoles antenna element to be shortened by as much as twenty percent without reducing the feed-line length.

Antennas | Broadband UHF Panels, UHF Slot, VHF Dipoles, FM FM Dipoles UHF Circular Polarized Panels In addition to a standard portfolio of UHF, VHF and FM broadcast antennas, Mega Industries designs, builds and tests custom antennas from 50 MHz to 12 GHz in a variety of configurations including traveling wave, phased array and horn-fed reflectors. A SHALLOW-CAVITY UHF CROSSED-SLOT ANTENNA The shallow-cavity crossed-slot antenna is a UHF radiator designed primarily for use on a high-speed aircraft operating as the airborne terminal in a satellite-to-air communications link. The require- ments, design analysis and performance characteristics are de- scribed. The antenna's shallow profile makes it attractive either as US6414647B1 - Slender omni-directional, broad-band, high
