The antennas listed below are available in the Antenna Magus database. For each of these antennas, Antenna Magus offers detailed information, synthesis algorithms, performance estimations and ready-to-run simulation models. Dual Pol - National Oceanic and Atmospheric Administration This poster will present a slot-dipole dual polarized radiating element design and performance. A panel of 144 dual pol elements was fabricated and characterized in the far field RF anechoic chamber to demonstrate cross pol performance across the operating S-band frequency and scan volume. An interactive simulation was developed to extrapolate the measured slot-dipole element performance and demonstrate the panel co-pol and cross-pol patterns for any azimuth and elevation angles. The test ...

IEEE Xplore: IEEE Antennas and Wireless Propagation ... A novel dual-polarized dipole antenna for base-station applications is presented in this letter. The proposed antenna is composed of a cross dipole, a square loop, a square plate, and a small-size reflector. The square loop and the square plate act as a parasitic radiator and a director, respectively. US4710775A - Parasitically coupled, complementary slot ... A parasitically coupled, complementary slot dipole antenna element includes a driven, cavity-backed slot antenna element and a parasitic dipole element transverse to the slot of the cavity-backed slot antenna element. The cavity-backed slot and parasitic dipole antenna elements resonate at about the center frequency of the excitation signals supplied to the cavity-backed slot antenna element ...
