Abstract
A window antenna wherein three embedded wires are laminated inside a glazing and a connector is attached to the joint end of the first and second wires and a signal input. The second antenna wire is longer and resonates at a lower frequency than the first antenna wire. A third antenna wire is a parasitic L-shape wire with part of the wire in close distance to the open end of the second antenna wire. The third antenna wire is electromagnetically coupled to the second antenna wire in the near field so that the antenna may support an additional resonance to provide multiband and wideband performance.
