Patent number: 9838046Abstract: An electronic device has wireless communications circuitry that includes transmitters and receivers. Antenna structures may be coupled to the transmitters and receivers to support radio-frequency signal transmission and radio-frequency signal reception operations. Switching circuitry such may be used to support multiple communications bands of interest. One or more low band receivers may be associated with the first switch and one or more high band receivers may be associated with the second switch. The switches can be configured in real time to switch a desired communications band into use. A diplexer may be used to simultaneously pass low bands to the first receiver and high bands to the second receiver. In this way, a data stream in the low band may be simultaneously received with a data stream in the high band.Type: GrantFiled: December 28, 2015Date of Patent: December 5, 2017Assignee: Apple Inc.Inventors: Nicholas W.

Patent number: 8892049Abstract: Handheld electronic devices are provided that contain wireless communications circuitry. The wireless communications circuitry may include an antenna. A radio-frequency coupler may be coupled to the antenna. Transceiver circuitry may be used to transmit and receive radio-frequency signals through the coupler and the antenna. A reflected power detection circuit may be connected to the coupler. When the transceiver circuitry transmits radio-frequency signals, some of the signals are reflected back from the antenna into the coupler. The coupler directs the reflected antenna signals into the reflected power detection circuit. Processing circuitry may analyze a reflected power signal from the reflected power detection circuit to determine whether operation of the antenna is being disrupted by the placement of a user's hand over the antenna or other proximity effects. If antenna operation is being disrupted, the user may be alerted or other suitable actions may be taken.Type: GrantFiled: October 10, 2007Date of Patent: November 18, 2014Assignee: Apple Inc.Inventors: Michael N.

Patent number: 8666328Abstract: An electronic device has wireless communications circuitry that includes transmitters and receivers. Antenna structures may be coupled to the transmitters and receivers to support radio-frequency signal transmission and radio-frequency signal reception operations. Switching circuitry such as first and second radio-frequency switches may be used to support multiple communications bands of interest. A low band set of transmitters may be associated with the first switch and a high band set of transmitters may be associated with the second switch.
