    摘要: A multiband antenna includes a 5-6 GHz PIFA surrounded on two or three sides by a 2.4 GHz RFPIFA. The PIFA and RFPIFA are tunable by removing fingers from the PIFA and either removing portions of or creating at least one area in the RFPIFA where inductance may be added. The RFPIFA contains an inductive meanderline. An out-of-plane matching stub is provided between the feed and the ground plane to impedance match the antenna. The PIFA/RFPIFA is supported by a plastic mesa tabletop whose legs are mounted directly to the ground plane of a PCB at the corner of the PCB. Electronic components on the PCB can be mounted underneath the multiband antenna.

    摘要: A battery is provided for an electronic device that includes contacts on inside and outside surfaces of the battery enabling additional batteries to be stacked on the battery in use. With respect to a cellular phone, this arrangement enables an operator to add additional talk time without requiring the operator to terminate a call. The battery casing is shaped corresponding to the electronic device to maximize battery capacity while minimizing size. In one arrangement, the male terminals that are not in use are retracted within the battery casing, and a sensor assembly senses the attachment of an auxiliary battery and extends the male contacts outside of the battery casing. The configuration allows greater choice of battery capacity and also permits the addition of more batteries as one is depleted.

    摘要: A coplanar antenna connector which interconnects an antenna and a printed circuit board of a portable radiotelephone is described. In particular, the antenna connector includes an antenna connector conductor strip having opposing first and second ends adapted for transmitting a radiotelephone signal from a source to an antenna or from an antenna to a receiver. The connector also includes at least one antenna connector ground strip having first and second opposing ends adapted for transmitting a radiotelephone signal. The at least one antenna connector ground strip and the antenna connector conductor strip are held in coplanar alignment, preferably by a nonconducting carrier ribbon. Each of the at least one antenna connector ground strips and the antenna connector conductor strip are spaced-apart and define a gap therebetween. The flexible antenna connector provides an easy, cost effective connection between the antenna and the printed circuit board in a manner which minimizes the amount of printed circuit board space needed therefor. The connector is also easily adaptable for use with retractable antennas. Also described are radiotelephones, portable radiotelephone antenna assemblies, and related radiotelephone assembly methods employing a flexible antenna connector.

    摘要: Electromagnetic shielding devices are provided with walls having a pair of opposing, generally parallel side faces that terminate at a tapered end portion. Each tapered end portion is configured to be surface mounted to a respective conductive portion (e.g., mounting pad) of an electronic substrate via a pair of solder fillets. The tapered end portion of each wall includes a pair of elongate end faces symmetrical about a plane that is generally parallel to, and equidistant between, the wall side faces. The end faces define a pair of elongated cavities with respect to a PCB that are configured to receive the solder fillets.

    摘要: A resonator (50) is connected in circuit with a negative resistance element (Q3,Q4) for producing oscillation at a resonant frequency of the resonator (50). A digital phase shifter (58) is incorporated into the resonant frequency in accordance with an applied digital signal. The resonator (50) can be connected in series with the negative resistance element (Q3), in which case the phase shifter (58) is connected as either a short-circuit or an open-circuit transmission line. Alternatively, the resonator (50) can be connected in parallel with the negative resistance element (Q4) in a feedback loop. An analog phase shifter (84) can also be provided in the resonator (50') for continuously variably setting the resonant frequency over the tuning increments of the digital phase shifter (58).

    摘要: A coplanar waveguide directional coupler (116,134) may be formed on a surface (102a,106a) of a substrate (102) and/or a microwave monolithic integrated circuit (MMIC) chip (106), with the MMIC chip (106) being flip-chip mounted on the substrate (102). The directional coupler (116,134) includes an input port (114,136), a coupled port (126,154), a direct port (122,152) and an isolation port (1118,150) formed on the surface (102a,106a). At least two parallel first striplines (24,26) are formed on the surface (102a,106a), having first ends connected to the input port (114,136) and second ends connected to the direct port (122,152). At least two parallel second striplines (36,38) are formed on the surface (102a,106a), having first ends connected to the coupled port (126,154) and second ends connected to the isolation port (118,150). The second striplines (36,38) are interdigitated with the first striplines (24,26) to provide tight signal coupling therebetween. First and second main ground planes (52,54) are formed on the surface (102a,106a) and extend parallel to and on opposite respective sides of the interdigitated first and second striplines (24,26,36,38). The input port (114,136), coupled port (126,154), direct port (122,152) and isolation port (118,150) each include a coplanar waveguide section having a center conductor (14a,16a,18a,20a) connected to the ends of the respective striplines (24,26,36,38), and first and second ground planes (14b,14c), (16c,16c), (18b,18c, (20b,20c) which extend parallel to the center conductor (14a,16a,18a,20a) on opposite sides thereof and are connected in circuit to the main ground planes (52,54).

    摘要: A coplanar waveguide based microwave monolithic integrated circuit (MMIC) oscillator chip (14) having an active oscillator element (16) and a resonant capacitor (18) formed thereon is flip-chip mounted on a dielectric substrate (12). A resonant inductor (22) is formed on the substrate (12) and interconnected with the resonant capacitor (18) to form a high Q-factor resonant circuit for the oscillator (10). The resonant inductor (22) includes a shorted coplanar waveguide section (24) consisting of first and second ground strips (24b,24c), and a conductor strip (24a) extending between the first and second ground strips (24b,24c) in parallel relation thereto and being separated therefrom by first and second spaces (26a,26b) respectively. A shorting strip (24d) electrically interconnects adjacent ends of the conductor strip (24a) and first and second ground strips (24b,24c) respectively. A dielectric film (34) may be formed over at least adjacent portions of the conductor strip (24 a) and first and second ground strips (24b,24c). The resonant inductor (22) is adjusted to provide a predetermined resonant frequency for the oscillator (10) by using a laser (40) to remove part of the dielectric film (34) in the first and second spaces (26a,26b) for fine adjustment, and/or to remove part of the shorting strip (24d) at the ends of the first and second spaces (26a,26b) for coarse adjustment.

    摘要: A flip style cellular telephone includes a main housing, a microphone mounted in the main housing and a flip, pivotably mounted to the main housing by a hinge. The flip is formed with an acoustic pipe on a peripheral edge of the flip. The acoustic pipe extends from the free end to the hinged end of the flip, and includes a plurality of holes for a sound inlet at the free end of the flip. The hinge is hollow, and the acoustic pipe connects with the microphone through the hollow hinge. Sound of the user's voice is carried by the acoustic pipe from the inlet to the microphone. The acoustic pipe advantageously only minimally changes the profile and aesthetics of the telephone.
