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 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: Una disposición de antena de doble banda para usar en dispositivo portátil para comunicaciones se revela en el presente. La disposición de antena incluyeun elemento de antena para irradiar energía electromagnética dentro de rangos de longitud deo nda de banda alta y de banda baja. En un ejemplo preferido, unared aislante de banda baja, acoplada al elemento de antena, provee aislación de senal entre los caminos de senal de banda alta y de banda baja durante laoperación de banda alta. Demanera similar, una red aisladora de banda alta provee aislación de senal, durante la operación sobre el rango de longitudesde onda de banda baja, entre los caminos de senal de banda baja. Durante la operación de transmisión y recepción, laenergía electromagnética de banda altadirigida a través de la antena pasa por las redes aisladoras de banda baja y de banda alta, respectivamente. También se incluyen redes equilibradoras debanda alta y de banda baja que acoplan las redesaisladoras de b anda alta y de banda baja a circuitos transceptores de banda baja y de banda alta.

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.
