Abstract
An antenna arrangement comprises at least two antenna loops disposed in two intersecting planes disposed at an angle to define a detection region in which the antenna loops transmit and/or receive electromagnetic signals and through which an object may pass. Each antenna loop includes a portion disposed in each of the two planes, and the antenna loops overlap at least in part in each of the two planes. The antenna arrangement may be coupled to a processor and/or utilization system for cooperating therewith for performing a desired function.
