An integrated antenna and input device is provided that includes an antenna for transmitting and/or receiving electronic signals, and strain sensing elements coupled to the antenna. The strain sensing elements detect directional movement of the antenna. Additionally, an electronic communication device is provided. The device includes a graphical display, a control circuit, an antenna, and at least one sensor. The control circuit displays information on the graphical display, and the antenna transmits and/or receives electronic signals. The sensor is coupled to the antenna and the control circuit, and relays directional movement of the antenna to the control circuit to navigate the displayed information or select specific functions of the communication device.

Integrated antenna and input device

An antenna feedpoint assembly includes a printed circuit board (,), a signal conductor feed element (,) mounted on the printed circuit board (,), and a secondary ground element (,) placed parallel to the signal conductor feed element (,) wherein an electromagnetic coupling is made between the signal conductor feed element (,) and the secondary ground element (,) for an improved matching of the antenna (,) without an additional matching circuit. The secondary ground element (,) comprises a mounting portion (,) connected to a ground plane (,) and a protruded portion (,) extended from the mounting portion (,) such that the protruded portion (,) is elevated from and substantially parallel to the signal conductor feed element (,) serving as the antenna feedpoint contact.

Secondary antenna ground element

In one embodiment of the invention, an antenna (,) includes an antenna cavity used for receiving a removable stylus (,). A retention feature such as a snap (,) helps retain the stylus (,) to the antenna (,) when not in use. In an alternate embodiment, the stylus (,) is an inlay to the outer wall of antenna (,). In still another embodiment of the invention, a removable antenna stylus (,) serves as an antenna when attached to radio (,) and as a stylus when removed from the radio (,).

An antenna system includes a main antenna (,) and a parasitic element (,). The parasitic element (,) is rotatably coupled (,) to the main antenna (,), the antenna system being movable from a closed position to an open position, in which the main antenna (,) is coupled to the parasitic element (,) to cause the parasitic element (,) to operate as a passive radiator element and to radiate (,) along with the main antenna (,) to enhance the gain of the antenna system.

Passive flip radiator for antenna enhancement

An antenna assembly includes a straw having a substantially linear passageway and a helix base coil with an angled tapered guide, the passageway having a width wider than the widest portion of the angled tapered guide. An antenna element has a stopper portion and a straw. For a vertical retraction and a slanted extension, the antenna element is movable between a slanted position wherein the antenna element is inclined from the housing when the stopper of the antenna element is positioned inside the angled tapered guide of the base coil and a retracted position substantially within the straw inside the radio housing wherein the antenna element is retracted vertically within the straw.

Retractable angled antenna assembly

An antenna coupling assembly (100) includes an stub section (107) for coupling radio frequency (RF) energy from an RF source to a radio antenna. An antenna coupler ground (113) is positioned adjacent to the stub section (107) and is electrically connected to the ground of the RF source (101). In accordance with the invention, a ground extension section (115,115',115') is attached to the antenna coupler ground (113) for electrically extending the physical length of the antenna coupler ground to enhance efficiency and overall performance of the antenna coupler.

Radio frequency (RF) antenna coupler with an electrically extended

An antenna coupler (100) for use in a mobile adaptor (102, 300) transfers radio frequency (RF) energy between a portable radio antenna system (204) and an external antenna (124) with minimal coupling losses. The antenna coupler (100) includes a resonator patch (110) and an electromagnetic tuning element (112) forming side walls on a substrate for receiving the portable antenna system (204). The electromagnetic tuning element (112) controls the impedance between the resonator patch (110) and the portable antenna system (204) while the resonator patch transfers the RF energy between the portable radio antenna and the external antenna (124).
