Folded planar antenna

Abstract:

An antenna structure associated with a wireless communication device comprised of a plurality of structures configured to enable structural, functional or cosmetic functions associated with the device, is proposed in this disclosure. The antenna structure comprises a first plate comprised of a first set of structures of the plurality of structures of the device and a second, different, plate comprised of a second set of structures of the plurality of structures of the device. The antenna structure further comprises an excitation component coupled between the first plate and the second plate. In some embodiments, the first plate, the second plate and at least a part of the excitation component are configured to form a tank circuit, thereby enabling the antenna structure to radiate at a predefined radiation frequency comprising a resonant frequency associated with the tank circuit.
