ANTENNA FOR TIRE PRESSURE MONITORING WHEEL ELECTRONIC DEVICE

摘要

An antenna system for a radio frequency (RF) electronic device includes a printed circuit board (PCB), a ground plane, and an active element. The PCB may have a top surface and a bottom surface. The ground plane may be on the bottom surface. The active element may be mounted on the top surface. The active element includes a first segment positioned in a top surface plane and connected to a second segment oriented perpendicular to the top surface.
