Patent number: 9570813Abstract: A user device having a dielectric carrier, a multi-band slot antenna, a reflector and a feed line connector is described. The multi-band slot antenna has slot openings in a second portion of conductive material disposed on a second side of the user device and is operable to radiate electromagnetic energy. The reflector is additional conductive material disposed on the second side and is operable to reflect a majority of the radiated electromagnetic energy away from the user device in a first direction.Type: GrantFiled: May 16, 2014Date of Patent: February 14, 2017Assignee: Amazon Technologies, Inc.Inventor: Weiping Dou

Patent number: 9490864Abstract: A wireless electronic device having first and second baseband processors is provided. In one suitable arrangement, radio-frequency power splitters and adjustable low noise amplifiers may be form in the receive paths. The use of power splitters allow signals associated with the first and second baseband processors to be received in parallel. In another suitable arrangement, radio-frequency switches are used in place of the power splitters. The states of the switches may be controlled using at least one of the first and second baseband processors. The use of switches instead of power splitters requires that wake periods associated with the first baseband processor and wake periods associated with the second baseband processor are non-overlapping. To ensure minimal wake period collision, a wake period associated with the second baseband processor may be positioned at a midpoint between two successive wake periods associated with the first baseband processor.Type: GrantFiled: May 12, 2014Date of Patent: November 8, 2016Assignee: Apple Inc.Inventors: Syed A.

Patent number: 8958760Abstract: Electronic devices may have multiple wireless integrated circuits such as a pair of baseband processor integrated circuits and may have multiple antennas such as a pair of antennas. An electronic device may be operated in different modes depending on the operating environment of the electronic device. When both antennas are unblocked, both baseband processors and both antennas may be used in transmitting signals. When one antenna is not available, the device may be operated in a mode in which the available antenna is used and both baseband processors are used or in a mode in which the available antenna is used and only one of the baseband processors is used. Operating mode decisions may be made so as to minimize the potential for intermodulation distortion and absorbed radiation.Type: GrantFiled: January 9, 2012Date of Patent: February 17, 2015Assignee: Apple Inc.Inventors: Syed A. Mujtaba, Weiping Dou
