Antenna arrangement
First Claim
1. An antenna arrangement, comprising:
- a first antenna module, including;
a first antenna loop positioned in a plane and configured to emit a signal in a first spatial area;
at least one additional antenna loop positioned in substantially the same plane and configured to emit a signal in an additional spatial area; and
at least one power source in communication with the first antenna module and configured to provide current thereto;
wherein the first spatial area and the additional spatial area at least partially overlap;
wherein the first antenna loop and the additional antenna loop are configured to be powered by the power source in specified pattern.

Abstract
An antenna arrangement including a first antenna module having a first antenna loop positioned in a plane for emitting a signal in a first spatial area, and at least one additional antenna loop positioned in substantially the same plane for emitting a signal in an additional spatial area. The arrangement includes at least one power source in communication with the first antenna module for providing current thereto. The first spatial area and the additional spatial area at least partially overlap, and the first antenna loop and the additional antenna loop are powered by the power source in a specified pattern. A method of identifying at least one item is also disclosed.
