ANTENNA DEVICE |
摘要 |
An antenna device has at least one antenna element with two radiators disposed on a retainer member. The retainer member may be a separate unit but may also constitute an integral part of a casing for a cell or mobile telephone. In order to provide superior antenna performance and simple impedance adaptation, the radiators are connected in parallel and are designed so that they have a surface extent which is shaped to conform closely with the shape of interior surfaces of the casing. In one embodiment, there is an outer radiator which has a connecting portion which is located physically proximal the antenna element in order thereby to realize a capacitative/inductive connection of the outer radiator to the antenna element. |
