Abstract: A double helix antenna (10) comprised of orthogonally-wound helix conductors . The double helix antenna (10) includes a first helix conductor (14) wound in a first direction about a vertical axis, V, of the double helix antenna (10). A second helix conductor (18) is wound in a second direction about the vertica l axis, V. In a specific implementation, the first and second helix conductors (14 and 18) are of different lengths, respectively corresponding to first an d second frequency bands. Additionally, the first and second helix conductors (14 and 18) are wound so as to be orthogonal at those horizontal planes with in which the first and second helix conductors (14 and 18) intersect or are otherwise minimally separated in the horizontal dimension. This orthogonal winding relationship between the helix conductors substantially reduces mutu al coupling, thus enabling operation of separate helical antennas in close physical proximity.

Abstract: A connector interface 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 comprised of an outer conductive shell, a nonconductive spacer and a ground probe. The outer conductive shell is mounted on the printed circuit board. The nonconductive spacer is disposed within the hollow pseudo-cylindrical center of the outer conductive shell. When the connector interface is connected to the wireless communication device, the outer conductive shell 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 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: A balanced dipole antenna (600) for a mo- bile phone comprises a radiator element (604) and a counterpoise (608), both formed of a con- ducting material. The counterpoise is electrically isolated from the ground plane of a printed wire board (PWB) (612) of the mobile phone. A matching network, for example, a balun (616, 900, 1000, 1100), provides balanced current to the dipole antenna, resulting in a symmetric radi- ation pattern. The balanced dipole antenna (600) allows superior performance over conventional antennas found in mobile phones today by en- abling a user of a mobile phone to communicate effectively and uniformly in all directions, that is, 360 degrees.

Abstract: A double helix antenna comprised of orthogonally-wound helix conductors is disclosed. The double helix antenna system includes a first helix conductor wound in a first direction about a vertical axis of the double helix antenna. A second helix conductor is wound in a second direction about the longitudinal axis. In a specific implementation, the first and second helix conductors are of different lengths, respectively corresponding to first and second frequency bands. Additionally, the first and second helix conductors are wound so as to be orthogonal at those horizontal planes within which the first and second helix conductors intersect or are otherwise minimally separated in the horizontal dimension. This orthogonal winding relationship between the helix conductors substantially reduces mutual coupling, thus enabling operation of separate helical antennas in close physical proximity. In a particular application, the double helix antenna system is incorporated within a portable communications device.

Abstract: Se expone en la presente un sistema de antena de doble banda para utilizarse en un dispositivo de comunicaciones. El sistema de antena incluye un elemento de antena (10) para irradiar energía electromagnética dentro de rangos de longitud de onda de banda baja y de banda elevada. En una modalidad preferida, una red aisladora de bandeja (20), acoplada al elemento de antena (10), proporciona aislamiento de señal entre las trayectorias de banda elevada y de banda baja durante la operacion de banda elevada. De manera similar, una red aisladora de banda elevada (18) proporciona el aislamiento de señal, durante la operacion sobre el rango de banda baja de longitudes de onda, entre las trayectorias de señal de banda elevada y de banda baja. Durante la operacion de transmision y recepcion, la energía electromagnética de banda baja y de banda elevada dirigida a través de la antena (10) se pasa mediante las redes aisladoras de banda baja y de banda elevada, (20) y (18), respectivamente. También se incluyen redes de comparacion de banda baja y de banda elevada (28) y (36), respectivamente, las cuales acoplan las redes aisladoras de banda baja y de banda elevada (20) y (18), respectivamente a la circuitería transceptora de banda baja y de banda elevada.

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.
