Abstract:
1. An antenna that has an impedance and that is fed by a transmission line that has a first conductor and a second conductor, wherein the transmission line has an impedance, comprising: a ground plane element connected to the first conductor; at least one antenna resonating element opening formed in the ground plane element; and a planar conductive structure that bridges at least part of the antenna resonating element opening and that is connected to the second conductor, wherein the planar conductive structure has an area and is operable to, together with the ground plane element, create a feed capacitance to match the impedance of the transmission line to the impedance of the antenna, wherein the at least one antenna resonating element opening comprises first and second antenna resonating element slots, wherein the planar conductive structure overlaps a first part of the first slot, and wherein the second conductor overlaps the second slot and overlaps a second part of the first slot.
