Phased-Array Antenna Radiator Parasitic Element for a Super Economical Broadcast System

摘要

A parasitic element for a phased-array antenna radiator is provided. The radiator comprises a first dipole radiator including two coplanar monopole radiating elements disposed symmetrically about a radiation axis, a second dipole radiator, arranged orthogonally with respect to the first dipole radiator, including two coplanar radiating elements disposed symmetrically about the radiation axis, and a parasitic gain element, having a substantially elliptical shape, disposed above the first and second dipole radiators and centered on the radiation axis.
