Shaped-beam horn-reflector antennas
WebbThis paper presents the generation of orbital angular momentum (OAM) vortex waves with mode +1 using dielectric resonator antenna (DRA) array. The proposed antenna was designed and fabricated using FR-4 substrate to generate OAM mode +1 at 3.56 GHz (5G new radio band). The proposed antenna consists of 2 × 2 rectangular DRA array, a … WebbThese dipole-array antennas reduce in size from the back end to the front end. The leading beam of this RF antenna comes from the smaller front end. Log Periodic Dipole Antenna The element at the back end of the …
