Abstract
An antenna structure including a dual-band WiFi CPW antenna formed on a dielectric substrate and a frequency selective impedance surface formed on the substrate and at least partially surrounding the antenna. The antenna includes a ground plane defining a gap and an antenna radiating element including a radiating portion positioned proximate to the ground plane and a feed line extending into the gap. The frequency selective impedance surface can be a ring that is configured around the radiating portion of the radiating element, where the frequency selective impedance ring receives surface waves propagating along the dielectric substrate generated by the antenna.
