Abstract: Apparatuses and methods are disclosed for determining a dominant figure-of-merit for an antenna system comprising a primary antenna, and at least two diversity antennas. The dominant figure-of-merit is determined from at least two figure-of-merit types related to performance of the primary antenna when paired with one or the other of the at least two diversity antennas. The disclosed apparatuses and methods include switching to one or the other of the at least two diversity antennas, to obtain the dominant figure-of-merit, in response to a signal quality metric's relationship to the at least two figure-of-merit types.

Abstract: An electronic device (200) includes a single antenna (211), a communication circuit (202), and a RFID circuit (207). A switch (212) selectively couples the single antenna to one of the communication circuit or the RFID circuit. For example, the RFID circuit can be coupled to the single antenna when the electronic device is OFF, and the communication circuit can be coupled to the single antenna when the electronic device is ON. Accordingly, RFID information can be received from an RFID communication device when the electronic device is OFF. When the electronic device is ON, an interrupt can cause the switch to connect the RFID circuit to the single antenna, sometimes only for less than a predetermined duration.

Abstract: Aspects of the present disclosure teach decreasing, in a time-averaged regime, the amount of RF energy emitted by a communications device. Generally speaking, the network tells the communications device what power level it should transmit at. If, however, the device determines that it would exceed an emission standard by transmitting at the specified power level for as long as it needs to in order to carry out its transmission duties, then the device can instead decide to transmit at a lower power level. Alternatively (or in combination), the device can, instead of transmitting all the time while it has data to send, only transmit intermittently. In either case, the emitted electromagnetic energy, as averaged over a period of time, is reduced below the maximum allowed by the standard. Later, if possible and necessary, the device can again transmit at a higher power level or more frequently.

Abstract: An electronic device, such as a mobile radiotelephone, includes a dual antenna structure with a selectively actuatable phase shifter disposed therebetween. When the selectively actuatable phase shifter is selected, signals received by the first and second antennas are substantially out of phase. When the selectively actuatable phase shifter is not selected, signals received by the first and second antennas are substantially in phase. The dual antennas are coupled to a first electrical circuit disposed in a first section of the device. A second electrical circuit is disposed within a second section of the device. An impedance element, for example an inductor, couples the first and second electrical circuits and is disposed in a substantially symmetric location between the first and second electrical circuits. Working in combination, when the selectively actuatable phase shifter is selected, an antenna pattern of the device becomes substantially azimuthal with a null at a top central location.
