A communications device includes a cover member, a circuit board having a lowest point of potential, and an antenna to transmit and receive RF signals. The antenna is electrically connected to the circuit board. A carrier is interposed between the circuit board and the cover member. The carrier includes an electrically conductive layer electrically connected to the point of lowest potential of the circuit board.

Electrically conductive carrier and patterning for controlling current distribution in a wireless communications device

A multiple antenna mobile communication device, such as a cellular telephone, having multiple radios and multiple antennas located in close proximity to each other uses a parallel tuning circuit to optimize the isolation between the antennas. The parallel tuning circuit can include multiple impedance matching circuits to match the impedance in multiple frequency bands or isolating antennas.

Multiple antenna impedance optimization

An antenna/push-button assembly includes a first contact, a second contact movable relative to said first contact, and a button member including an integral antenna. The button member is movable to engage the second contact with the first contact. The antenna may be a patch antenna. A portable telecommunications device includes an antenna/push-button assembly comprising a button member. The button member includes an integral antenna. The button member is operable to control a function of the device.

Antenna/push-button assembly and portable radiotelephone including the same

A wireless communications device includes an integrated antenna assembly that provides signals associated with multiple functions to the wireless communications device. The integrated antenna assembly includes an integrated antenna housing coupled to a radiotelephone housing and multiple antennas. The integrated antenna housing can include a first antenna that provides GPS signal reception for a GPS receiver and a second antenna that provides communications signals to and from a radiotelephone processor in the radiotelephone housing. The first and second antennas can be mounted on an antenna backing having a first face and a second face. The first and second antennas may be located on the same face of the antenna backing or on opposite faces of the antenna backing. The integrated antenna assembly also can include a third antenna located between the first and second antennas. In this case, the first and second antennas are high-band antennas and the third antenna, located therebetween, is a low-band antenna which can reduce the electromagnetic coupling between the first and second high-band antennas.
