An RFID antenna 100 comprises two or more electroconductive sheets 120a, b of uniform planar size, being parallel and aligned, with a space therein between. Each electroconductive sheet 120a, b comprises: a feed connection point 130a, which receives an electrical current from a feed 110 to supply current to the electroconductive sheet 120a, b; and a return connection point 130b, opposite and parallel to the feed connection point 130a of the electroconductive sheet 120a, b, which acquires current from the electroconductive sheet 120a, b and transfers current to a return 140. The electrical circuit pathway created from the feed 110 to the return 140 is equal distance for each electroconductive sheet 120a, b. The two electroconductive sheets 120a, b are connected together to complete a circuit that causes direction of electrical flow in the one electroconductive sheet 120a to be opposite to direction of electric flow in the other electroconductive sheet 120b. |
