LOW COST HIGH PERFORMANCE MULTIBAND CELLULAR ANTENNA WITH CLOAKED MONOLITHIC METAL DIPOLE

摘要

Disclosed is a high performance low cost multiband antenna configuration that has a low band dipole having dipole arms formed of stamped sheet metal with a plurality of inductor structures. The plurality of inductor structures are oriented along a longitudinal axis of the low band dipole arm, and others are oriented orthogonal to the longitudinal axis. The plurality of the inductor structures act as cloaking structures that make the low band dipole substantially transparent to high band RF energy without inhibiting the performance of the dipole in the low band.
