COMPACT DUAL-POLARIZED MULTIPLE DIRECTLY FED amp; EM COUPLED STEPPED PROBE ELEMENT FOR ULTRA WIDEBAND PERFORMANCE

摘要

A compact antenna element and assembly using a directly fed and electromagnetically coupled step probe element for ultra wideband application. It achieves very good impedance match, isolation and pattern stability across a wide frequency band. The compact ultra wideband radiating element covers all known radio frequency bands in the mobile base station industry to date.
