Abstract
A compact planar inverted F antenna suited for remote wireless metering includes a circuit element, a ground plane and a feed probe. The circuit element has a planar portion with a reactance window, and a narrowed tab that extends transverse to the planar portion and is connected to the ground plane. The reactance window and narrowed tab reduce the size of the circuit element. The feed probe is connected between the circuit element and the ground plane. The ground plane has conductive portions that are wrapped around a substrate to reduce the physical size of the ground plane. The length of the tab and thereby the distance between the planar portion and the ground plane is selected so that the feed probe is a radiating element. The antenna is compact with good isotropic characteristics and sensitivity to two perpendicular polarizations.
