Patent ID: 7233291

Claim:
A wireless communication device including an antenna structure, the antenna structure comprising a) a plurality of antenna portions each having a substantially planar radiating surface; b) a planar conducting ground portion, galvanically connected to each of the antenna portions; wherein the radiating surfaces of the antenna portions are substantially parallel to one another in a side-by-side relationship and are substantially parallel to the planar conducting ground portion located behind the antenna portions with respect to a direction of transmission of radiation from the antenna portions, and wherein the wireless communication device comprises first and second metal covers forming a casing, said planar conducting ground portion separated from said first and second metal covers by a dielectric material, and wherein said communication device includes an antenna housing fitted to said first and second metal covers, said antenna housing incorporating said antenna portions and said conducting ground portion of the antenna structure, and wherein said first and second metal covers are capacitively coupled by said dielectric material to said ground portion, thereby forming a further ground plane by the first and second metal covers.
