摘要： Flexible diversity antennas having gain and bandwidth capabilities suitable for use within small communications devices such as radiotelephones are provided. A core of flexible material has an electrical conductor embedded therewithin in a meandering pattern and is surrounded by a first layer of flexible dielectric material. At one end of the antenna, the first layer of dielectric material is surrounded by flexible conductive material. The flexible conductive material is surrounded by a second layer of flexible dielectric material. The portion of the antenna surrounded by conductive material serves as a tuning element, and the portion of the antenna not surrounded by conductive material serves as a radiating element. A flexible signal feed is integral with the antenna and extends outwardly from the flexible core.

摘要： A portable phone is disclosed as including a main housing, circuitry located within the main housing for operating the portable phone in a designated mode of communication, a support bracket assembly detachably coupled to the main housing, a flip cover rotatably secured to the support bracket assembly about a first axis, and an antenna coupled to the circuitry for transmitting and receiving signals in the designated communication mode associated with the flip cover. The flip cover is also rotatable about a second axis with respect to the support bracket assembly, which is substantially perpendicular to the first axis. The support bracket assembly includes a support bracket having a slotted portion at one end sized to receive an end of the main housing, a latching mechanism for coupling the support bracket to the main housing, a hinge mechanism located at the other end of the support bracket to rotatably couple the support bracket to the flip cover about the first axis, and a yoke having an annular step which captures the flip cover so it can rotate about the second axis. The designated mode of communication may be cellular and/or satellite.

摘要： A portable phone capable of operating in cellular and satellite modes of communication is disclosed as including a main housing, circuitry located within the main housing for operating the portable phone in the cellular mode, circuitry located within the main housing for operating the portable phone in the satellite mode, a first antenna coupled to the cellular circuitry for receiving and transmitting signals in the cellular mode, and a second antenna coupled to the satellite circuitry for receiving and transmitting signals in the satellite mode. The second antenna can either be mounted to the main housing of the portable phone or housed within a flip cover coupled to the main housing. If provided, the flip cover is coupled to the main housing so as to be rotatable about a first axis and a second axis substantially perpendicular thereto. The first antenna may extend from the main housing, be printed on a surface of the flip cover, or be housed within the flip cover adjacent the second antenna.

摘要： A device for connecting the RF signal circuitry of a portable phone and a plurality of antennas utilized to transmit and receive signals is disclosed. The connector device includes a female portion electrically coupled to the RF signal circuitry, with the female portion providing a plurality of ports for electrical coupling with the RF signal circuitry. A complementary male portion is also provided which is electrically coupled to the antennas, the male portion including a separate pin member connected to each antenna. Each pin member of the male portion is received within a corresponding one of the ports in the female portion as the male and female portions of the connector device are mated together. In this way, the RF signal circuitry and the antennas are electrically coupled. The antennas of the portable phone are integrated with a flip cover rotatably mounted to a phone base containing the RF signal circuitry, where the flip cover may be either fixedly or detachably secured to the phone base.

摘要： A coaxial cable assembly for connecting at least one antenna element with RF signal circuitry of a portable phone is disclosed. The portable phone includes a base portion in which the RF signal circuitry is located and a flip cover rotatably secured to the base portion in which the antenna elements are located. The flip cover is rotatably secured to the base portion by means of a support bracket assembly. The coaxial cable assembly provides a separate coaxial cable for each antenna element, with a first end thereof being coupled to the antenna element and a second end being coupled to the RF signal circuitry. Each coaxial cable is shaped to extend through the support bracket assembly so as to withstand bend stresses associated with rotation of the flip cover, with certain locations of the coaxial cable being formed to maintain such shape.

摘要： A flip cover and antenna assembly for a portable phone is disclosed as being rotatably coupled to a main housing thereof. The flip cover and antenna assembly includes a first flip cover housing, a second flip cover housing matable with the first flip cover housing, and an antenna element positioned between the first and second flip cover housings. The antenna element further includes a ground plane bonded to the ground plane first surface. A dielectric foam is positioned over any remaining area of the ground plane first surface. The first and second flip cover housings have flanges which extend from at least a portion thereof to wrap around corresponding edges of the main housing, which enables extensions of the ground plane to be provided conforming to the flanges. The ground plane may also be patterned in order to control the radiation pattern thereof and limit any interference from other components of the portable phone. The flip cover and antenna assembly may also include a second antenna in the form of a printed circuit antenna or a monopole antenna.
