    Abstract: Dynamic tuning of antennas towards a receive channel carrier frequency, a transmit channel carrier frequency, or between the receive channel and transmit channel carrier frequencies in frequency division duplex (FDD) communications systems is disclosed. A user device, such as a mobile communications device may be configured to dynamically tune its antenna based at least in part on the amount of data to transmit, data to receive, a receive channel quality, and/or a transmit channel quality. The antenna may be tuned to one of the transmit or receive channels or a frequency between the transmit and receive channels based at least in part on which channel, if any, may benefit from greater antenna efficiency.

    Abstract: Antenna structures and methods of operating the same are described. One antenna structure having a stacked patch antenna including a first patch structure disposed in a first plane and a second patch structure disposed in a second plane, a first parasitic patch antenna that is coplanar with the second patch structure, and a second parasitic patch antenna that is coplanar with the second patch structure. The first patch structure includes a first substrate with a ground plane and a first patch element. The second patch structure includes a second substrate with a second patch element. The first parasitic patch antenna is disposed adjacent a first side of the second patch structure in the second plane. The second parasitic patch antenna is disposed adjacent a second side of the second patch structure in the second plane.

    Abstract: Antenna structures and methods of operating the same are described. One apparatus includes a metal cover having a first corner ground element, a second corner ground element, a first strip element, a second strip element, a radio frequency (RF) feed, and a RF circuit. The first strip element is physically separated from the first corner ground element by a first cutout in the metal cover. The first strip element is physically separated from the second strip element by a second cutout in the metal cover. The second strip element is physically separated from the second corner ground element by a third cutout in the metal cover. The RF circuitry is coupled to the RF feed, where the RF circuitry is operable to cause the first corner ground element and the first strip element as well as the second corner ground element and the second strip element to radiate electromagnetic energy.

    Abstract: Antenna structures and methods of operating the same of an electronic device are described. One apparatus includes a single radio frequency (RF) feed and a folded monopole element coupled to the single RF feed. The folded monopole element is an integrated WAN/GNSS antenna that receives electromagnetic energy in a first frequency band and receives electromagnetic energy in a second frequency band. The first frequency band is a wireless area network (WAN) frequency band and the second frequency band is a global navigation satellite system (GNSS) frequency band. The apparatus further includes an impedance matching circuit coupled to the single RF feed. The impedance matching circuit includes a diplexer to extract out GNSS frequency signals received by the folded monopole element from WAN signals received by the folded monopole element.
