Higher order mode 3-D Corner Reflector Antenna

Dihedral Corner Reflector Backscatter Using Higher Order Reflections and Diffractions

The uniform theory of diffraction (UTD) plus an imposed edge diffraction extension is used to predict the backscatter cross sections of dihedral corner reflectors which have right, obtuse, and acute included angles. UTD allows individual backscattering mechanisms of the dihedral corner reflectors to be identified and provides good agreement w?ith experimental cross section measurements in the a...

Higher-order Mode Rectangular Dielectric Resonator Antenna for 5G Applications

The excitation of the higher-order mode, in rectangular dielectric resonator designed was explored to enhance the antenna gain and detailed elaboration is presented in this paper. The antenna was fed by a 50Ω microstrip line through an aperture cut in the ground plane. Besides avoiding spurious radiation, this feeding technique gives flexibility in controlling the amount of coupling in order to...

Three-Dimensional Comer Reflector Antenna

A reflector antenna utilizing three planar reflectors and a 3/4 X-unipole radiator is proposed. Calculations based on image and EMF-methods predict that the gain is about 5 dB greater than that of the two-dimensional comer reflector antenna, and that the input impedance is roughly between 50 and 75 9. Experiments conducted on the three-dimensional corner reflector antenna with rectangular comer...
