Abstract: The present invention represents an integrated antenna assembly comprising a cellular communications antenna and a satellite communications antenna. Such an antenna assembly can, therefore, be used for communications over either frequency range. A wireless telephone using this assembly can, therefore, operate with either a terrestrial cellular communications system or a satellite communications system. In a preferred embodiment of the invention, the satellite communications antenna is a quadrifilar helix antenna and the cellular communications antenna is a sleeve dipole. The whip portion of the sleeve dipole is positioned axially in the center of the quadrifilar helix antenna. This orientation permits operation in both the satellite and cellular frequency ranges without significant electromagnetic coupling.

Abstract: Una antena bipolar equilibrada (600) para un telefono movil que comprende un elemento radiador (604) y un contrapeso (608), ambos formados de un material conductor. El contrapeso esta aislado electricamente del plano de tierra de un tablero impreso de cables (PWB) (612) del telefono movil. Una red de acoplamiento, por ejemplo, un acoplador (616, 900, 1000, 1100), suministra una corriente equilibrada para la antena bipolar, dando como resultado un patron simetrico de radiacion. La antena bipolar equilibrada (600) permite un funcionamiento superior sobre las antenas convencionales encontradas en los telefonos moviles actuales, haciendo posible que el usuario de un telefono movil se comunique de manera efectiva y uniforme en todas las direcciones, o sea, en 360°.

Abstract: The balanced, retractable dipole antenna comprises a first radiator element that is selectively extendable from, and retractable into, a mobile phone casing, a second radiator element, and a counterpoise that is electrically isolated from a printed wire board (PWB) of a mobile phone. The balanced, retractable dipole antenna further comprises a signal balancing means couple d between a signal source and at least the second radiator element and counterpoise to generate first and second signals, respectively. The first a nd second signals are substantially equal in magnitude but out of phase by 180 degrees. When the first radiator is extended, the first signal is transferre d to the first and second radiator elements, and the second signal is transferred to the counterpoise. When the first radiator element is retracte d, the first signal is transferred to the second radiator, while the second signal is transferred to the counterpoise and the first radiator element. Th e first and second signals produce balanced currents, thereby producing a symmetric radiation pattern.

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 compact, low cost antenna communicates with low and medium earth orbit satellites. The antenna includes a plurality of micro-strip elements arranged about an axis and positioned to illuminate upper elevation angles. The micro-strip elements are perpendicular to each other and are oriented toward the horizon at 90 degree increments. Furthermore, the micro-strip elements are tilted at a 50 degree angle. A quadrifilar helix is positioned at the center of the micro-strip elements and positioned to illuminate lower elevation angles. The micro-strip elements generate an omni-directional field pattern in the azimuth plane. The quadrifilar helix generates a high-gain, narrow beam-width field pattern that is also omni-directional in the azimuth plane. The antenna provides improved immunity to specular ground reflections by limiting reception of signals below a threshold elevation angle. Also, the antenna provides continuous, uninterrupted communications by eliminating "dead" period associated with conventional parabolic dish antennas.

Abstract: A dielectric resonator antenna (100) having a resonator (104) formed from a dielectric material mounted on a ground plane (108). The ground plane (108) is formed from a conductive material. First and second probes (112, 116) are electrically coupled to the resonator (104) for providing first and second signals, respectively, to or receiving from the resonator (104). The first and second probes (112, 166) are spaced apart from each other. The first and second probes (112, 116) are formed of conductive strips that are electrically connected to the perimeter of the resonator (104) and are substantially orthogonal with respect to the ground plane (108). The first and second signals have equal amplitude, but 90 degrees phase difference with respect to each other, to produce a circularly polarised radiation pattern. A dual band antenna (200, 220) can be constructed by positioning and connecting two dielectric resonator antennas (204, 208; 224, 228) together. Each resonator (204, 208; 224, 228) in the dual band configuration (200, 220) resonates at a particular frequency, thereby providing dual band operation. The resonators (204, 208; 224, 228) can be positioned either side by side or vertically relative to each other.
