    Abstract: Antenna structures and methods of operating the same of a wideband dual-arm antenna of an electronic device are described. One wideband antenna includes a first feeding arm coupled to a radio frequency (RF) feed and a second feeding arm coupled to the RF feed. At least a portion of the second feeding arm is parallel to the first feeding arm. The wideband dual-arm antenna further includes a third arm coupled to the ground plane. The third arm is a parasitic ground element that forms a coupling to the first feeding arm and the second feeding arm. The parasitic element increases a bandwidth of the wideband antenna.

    Abstract: Antenna structures and methods of operating the same of an electronic device are described. One apparatus includes an antenna element and three matching circuits coupled to the antenna element.

    Abstract: A user device receives a command to transmit information at a transmit power level specified by a wireless carrier. The user device determines whether transmitting the information at the specified transmit power level using a first duty cycle will cause the user device to violate a condition. Responsive to determining that transmitting the information at the specified transmit power level using the first duty cycle will cause the user device to violate the condition, the user device determines a new duty cycle that is lower than the first duty cycle, and transmits the information using the new duty cycle.

    Abstract: A wideband antenna apparatus including a harmonically suppressed low band antenna is provided. The low band antenna is configured as a folded monopole antenna with patch coupling for resonance in a first frequency band. A patch portion of the low band antenna is widely separated from a folded feed portion of the low band antenna to avoid slot resonances above the first frequency band. The patch portion is relatively large to avoid folding of the patch portion that could introduce resonances above the first frequency band. The wideband antenna apparatus may also include a high band antenna proximate with the low band antenna. The high band antenna may be a folded monopole patch coupled antenna configured for resonating in a second frequency band. The high band antenna may optionally be configured like the low band antenna to suppress resonances of the high band antenna above the second frequency band.

    Abstract: Approaches are described for managing effects such as interference, crosstalk, and other types of noise in an electronic environment using a physical and/or electronic switch to improve antenna performance. For example, in the situation where the connector is connected to the device and no data and/or power is being transferred through the connector, the switch is caused to be open. In this situation, because the connector will be an electrically floating metal instead of a grounded metal due to the open switch, at least a portion of the radiated and/or received antenna signals will not couple to the connector. In the situation where the connector is connected to the device and is being used to transfer data and/or power, the switch is caused to be closed, which will result in the connector being grounded. In such a situation, at least a portion of the noise generated by the connector due to transferring data and/or power will be grounded instead of being coupled to the antenna.

    Abstract: Technologies directed to a control circuit using dynamic signal compression are described. A control circuit includes a front-end module (FEM) coupled to an RF cable, the FEM having a low-noise amplifier (LNA). The control circuit further includes an automatic gain control (AGC) circuitry coupled to the FEM. The AGC circuitry receives a first radio frequency (RF) signal having a first portion of one or more symbols and a second portion of one or more symbols. The AGC circuitry further amplifies the first portion to generate a first portion of an output signal. The AGC circuitry further compresses the second portion to obtain a second portion of the output signal. The AGC circuitry further sends a control signal to cause the FEM to change a gain state value of the LNA from a first value to a second value based on a comparison between a voltage of the output signal and a reference voltage.
