Resonant compound antenna structure

摘要

A resonant structure, antenna system and method for improving the wireless performance of an interior antenna of a vehicular or mobile device is disclosed. The resonant structure comprises an inductive section configured to inductively couple to an interior antenna and a capacitive section configured to capacitively couple to a ground plane. The inductive section and the capacitive section are communicatively coupled to each other. The interior antenna is configured to be contained in a device package.
