Abstract
The present invention relates to an antenna design, which is usable in accurate position determinations. The antenna comprises a cylinder-shaped housing, a ground plane, and a single choke ring, where the choke ring and the housing are part of the same entity. A single round-shaped patch element is connected by four legs onto a circuit board, so that a rotationally symmetric structure is achieved. The height of the patch element is less than the height of the choke ring. Differential feeding network is placed on the bottom surface of the circuit board, where the ground plane forms the top surface of the circuit board. Two circular polarizations are enabled simultaneously. A self-calibration loop is also made possible.
