1. An antenna system for a tire pressure monitoring radio frequency (RF) electronic device, the system comprising:
- a printed circuit board (PCB) having a top surface and a bottom surface;
a ground plane on the bottom surface; and
an active element mounted on the top surface, wherein the bottom surface is mounted on or near a metal object, the active element comprises a first “
C”
or “
U”
shaped segment positioned in a top surface plane and connected in series to a second “
C”
or “
U”
shaped segment that comprises an arch, the arch is curved in a plane, the plane on which the arch is curved is oriented perpendicular to the top surface to reduce coupling between the antenna system and the metal object, and the metal object comprises a wheel rim.
