  • Patent number: 8639302
    Abstract: The invention provides a portable communication device and enclosure therefor where separation of its antenna from the user's head is facilitated. The device comprises: a case; a speaker port; an antenna located in the bottom of the case; and a spacer located on the front of the case for resting against a cheek of a user of the device. When the device is held against the head of a user of the device with the spacer resting against a cheek of the user, the spacer biases the bottom of the device away from the user's head. The spacer may be located at a distance from the speaker port on the front of the case to comply with a Cellular Telephone Information Association (CTIA) test plan for Mobile Station Over the Air Performance.

  • Patent number: 8594750
    Abstract: A mobile wireless communications device and associated method of making same includes a housing and circuit board having a ground plane. Radio frequency (RF) circuitry and a processor are carried by the circuit board and operative with each other. An antenna is carried by the housing and operative with the RF circuitry. Audio circuitry is carried by the circuit board and operative with the RF circuitry and processor. An audio transducer assembly such as a receiver is carried by the circuit board and engages audio circuitry for carrying audio signals between the audio circuitry and speaker. A filter is mounted at the speaker for blocking RF energy from the antenna through the speaker to the ground plane and decoupling the antenna from the speaker and any other components on the circuit board to minimize any detuning of antenna impedance match and degradation in antenna gain.
