Abstract

A wireless communication device includes: a case that includes a dielectric member made of a first dielectric material, the dielectric member being coated with a coating layer made of a second dielectric material; a wireless communication circuit that is housed in the case; an antenna element that is electrically connected to the wireless communication circuit, the antenna element being made of aconductive material and provided on a surface of the dielectric member; and an adhesive layer that is disposed between the antenna element and the dielectric member to adhere the antenna element ontothe dielectric member, the adhesive layer being made of a third dielectric material.

Description

[0001] related application [0002] The present disclosure relates to subject matter contained in Japanese Patent Application No. 2007-230750 filed on Sep. 5, 2007, which is hereby incorporated by reference in its entirety. technical field [0003] The present application relates to wireless communication devices and antennas, which are suitable for use in mobile communication systems. Background technique [0004] There is known an antenna structure which is three-dimensionally designed by mounting an antenna element on the surface of a dielectric substrate. The antenna member is directly mounted on a housing of a compact wireless communication device such as a cellular phone, or mounted on a circuit board, and used as a built-in antenna. Depending on its structural configuration, the antenna structure is often referred to as a molded interconnect device (MID) antenna. [0005] The MID antenna is configured by providing the antenna as a compact modular member to be instal...
