Abstract: A connector interface (68) provides direct connection from a wireless communication device to a coaxial connector. The wireless communication device has a housing with an antenna connector. The antenna connector has a hollow pseudo-cylindrical center providing an opening through the housing. The connector interface has a custom connector (66) comprised of an outer conductive shell (72), a nonconductive spacer (76) and a ground probe (78). The outer conductive shell (72) is mounted on the printed circuit board (70). The nonconductive spacer (76) is disposed within the hollow pseudo-cylindrical center of the outer conductive shell (72). When the connector interface is connected to the wireless communication device, the outer conductive shell (72) contacts the antenna connector and the ground probe extends through the opening into the housing to connect electrically to a ground potential within the housing.

Abstract: A dual-band antenna system for use in a portable communications device is disclosed herein. The antenna system includes an antenna element for radiating electromagnetic energy within low-band and high-band wavelength ranges. In a preferred embodiment, a low-band isolator network, coupled to the antenna element, provides signal isolation between high-band and low-band signal paths during high-band operation. Similarly, a high-band isolator network provides signal isolation, during operation over the low-band range of wavelengths, between the high-band and low-band signal paths. During transmit and receive operation, low-band and high-band electromagnetic energy directed through the antenna is passed by the low-band and high-band isolator networks, respectively. Also included are low-band and high-band matching networks which couple the low-band and high-band isolator networks to low-band and high-band transceiver circuitry.

Abstract: A balanced dipole antenna for a mobile phone comprises a radiator element and a counterpoise, both formed of a conducting material. The counterpoise is electrically isolated from the ground plane of a printed wire board (PWB) of the mobile phone. A matching network, for example, a balun, provides balanced current to the dipole antenna, resulting in a symmetric radiation pattern. The balanced dipole antenna allows superior performance over conventional antennas found in mobile phones today by enabling a user of a mobile phone to communicate effectively and uniformly in all directions, that is, 360 degrees.

Abstract: Un Oscilador Controlado por Voltaje (VCO) de banda ancha utiliza un circuito resonante sintonizable en un rango amplio de frecuencias resonantes. El circuito resonante incluye elementos variables de voltaje de manera tal que la frecuencia resonante, y consecuentemente la frecuencia de oscilacion, pueden sintonizarse electronicamente. Los elementos variables de voltaje se configuran de manera tal que multiples voltajes de control determinan la frecuencia resonante. Se aplica un primer voltaje de control a un primer conjunto de elementos de sintonizacion y opera como un control burdo de la frecuencia resonante. Se aplica un segundo voltaje de control a un segundo conjunto de elementos de sintonizacion y opera como un control fino de la frecuencia resonante. Utilizar multiples voltajes de control en multiples elementos permite un VCO de banda ancha mientras mantiene una ganancia de VCX baja.
