Abstract: An antenna adapter for interfacing a portable radiotelephone with external equipment. In a preferred embodiment, a connector assembly includes a first connector portion that inserts directly into the radiotelephone's antenna port, replacing the normal antenna assembly. Matching electrical components on a circuit board are used to match the impedance of the antenna port of the portable radiotelephone. A second connector portion typically uses conventional RF connectors to couple the radiotelephone antenna port to external equipment.

Abstract: A novel and improved antenna adapter for interfacing a portable radiotelephone 200 with test equipment is disclosed. In a preferred embodiment, the adapter assembly comprises an RF connector 104 at one end of an elongated conductor 102 which connects directly to the radiotelephone's 200 antenna port, replacing the normal antenna assembly. The elongated conductor 102 makes electrical contact with an external ground 204 of the battery charging ports at the bottom of the radiotelephone 200 at another end. The RF connector 104 may be impedance-matched to minimize RF signal attenuation when connected to the RF test equipment. In an exemplary embodiment, the RF connector 104 comprises a 50 OMEGA impedance-matched SMA connector.

Abstract: A dual-band antenna coupler for use in an adapter for portable radiotelephone. A plurality of curved bands of metal are positioned on a ground plane, with at least two of the plurality of curved bands of metal being electrically isolated from the ground plane so as to couple radio frequency (RF) signals to and from the antenna of the portable radiotelephone. The isolated curved bands of metal couple RF signals between the antenna of the portable radiotelephone and first and second matching circuits designed to match the portable radiotelephone antenna at each of the respective frequency bands. A selector switch coupled to the output of the matching circuits selects the appropriate matching circuit output for connection to an external antenna. The adapter also includes at least one ground pin mounted on the ground plane. When the portable radiotelephone is interfaced with the antenna coupler, the ground pin makes electrical contact with a ground reference connection on the portable radiotelephone.

Abstract: A dual-band antenna coupler (100) for use in an adapter for portable radiotelephone (200). A plurality of curved bands of metal (204a-c) are positioned on a ground plane (102), with at least two of the plurality of curved bands (204a, 204b) of metal being electrically isolated from the ground plane (102) so as to couple radio frequency (RF) signals to and from the antenna (204) of the portable radiotelephone (200). The isolated curved bands (204a, 204b) of metal couple RF signals between the antenna (204) of the portable radiotelephone and first and second matching circuits (602, 604) designed to match the portable radiotelephone antenna (204) at each of the respective frequency bands. A selector switch (606) coupled to the output of the matching circuits (602, 604) selects the appropriate matching circuit output for connection to an external antenna (304). The adapter also includes at least one ground pin (206a-c) mounted on the ground plane (102). When the portable radiotelephone (200) is interfaced with the antenna coupler (100), the ground pin (206a-c) makes electrical contact with a ground reference connection on the portable radiotelephone (202a, 202b, 208).

Abstract: Un nuevo y mejorado acoplador de antena (100) util en un adaptador para un radioteléfono portátil (200). En una primer modalidad, se colocan una pluralidad de bandas curvas de metal (204a-204c) sobre un plano base (102), con al menos una de la pluralidad de bandas curvas de metal (204a-204c) estando eléctricamente aislada del plano base (102) a fin de acoplar las señales de RF hacia y desde la antena (204) de un radioteléfono portátil (200). Al menos un conector de base (206a, 206b, 206c) se encuentra montado sobre el plano base (102). Cuando se comunica un radioteléfono portátil (200) con el adaptador de antena (100), al menos un conector de base (206a, 206b, 206c) hace contacto eléctrico con los tornillos de ensamblaje (202a, 20b) o un ensamblador de base externa (208) de un puerto de carga de batería en el radioteléfono portátil (200). En una segunda modalidad, un conector adaptador (404) hace contacto directo con un componente de la cadena de RF del radioteléfono portátil (200). En una tercer modalidad un acoplador helicoidal (504) rodea la antena (204) del radioteléfono portátil (200).
