Slot and dipoles as dual antennas

The slot antenna, consisting of a narrow slit in a ground plane, is a very versatile antenna. With modification, it is amenable to waveguide, coplanar waveguide (CPW), coaxial, slot line, or microstrip feeding schemes and has been used in all aspects of wireless and radar applications.

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 The present invention is directed toward a dual linear or circular polarized antenna comprised of two orthogonally linearly polarized radiative elements. More specifically, the present invention is for a slender slot-dipole antenna, where the slot and the dipole are located in the same physical structure. Feed line interference to the antenna can be eliminated by including a centrally located

Slot Antenna Uses Dual Polarization | Microwaves & Radio… Improving upon previous dual-polarized antenna designs, the authors have developed a broad beamwidth slot antenna featuring low cross-polarization and high isolation. Dipole Antenna / Aerial Tutorial The dipole antenna or dipole aerial is one of the most important and commonly used types of RF antenna.As the name suggests the dipole antenna consists of two terminals or “poles” into which radio frequency current flows. This current and the associated voltage causes and electromagnetic or...

For the lower frequency band, a V-slot is loaded on the planar dipole for acting as a capacitive loading for having wide impedance matching of the antenna. Then, two additional smaller planar dipoles are placed and connected to the irregular short patch for achieving another wideband performance at the higher frequency band. Dual frequency, dual polarized, multi-layered microstrip slot ...
