Abstract
A cradle can be mounted in a vehicle, or other suitable location, for supporting a wireless dual-frequency telephone that includes an antenna. The cradle includes a plastic housing and a ground plane disposed in the housing. A trough-shaped feed coupler element is electrically connected to matching circuits and an input/output connector. A first parasitic coupler element is aligned with the feed coupler element, and connected to the ground plane, and electromagnetically couples signals having a first frequency to and from the antenna. Together, the elements hold the antenna of the telephone. Also, a second parasitic element is disposed adjacent the feed coupler element for electromagnetically coupling signals to and from the antenna, that have a second frequency. If desired, the ground plane is established by a first conductive board and a second conductive board elevated above the first board.
