Abstract: An antenna tuning circuit is disclosed. The antenna tuning circuit is configured to make multiple estimates on an antenna impedance at an antenna port and determine an optimum tuning state for antenna tuning based on the antenna impedance estimates. The antenna tuning circuit may be further configured according to various embodiments of the present disclosure to minimize impedance estimation error, reduce magnitude and/or phase disturbance during antenna tuning, and extrapolate antenna impedance estimates for both transmit and receive frequencies. As a result, the antenna tuning circuit can accomplish autonomous antenna tuning optimization to thereby improve transmit and receive performance in a wireless communication device.

Abstract: The present disclosure generally relates to the combination of MEMS intrinsic technology with specifically designed solid state ESD protection circuits in state of the art solid state technology for RF applications. Using ESD protection in MEMS devices has some level of complexity in the integration which can be seen by some as a disadvantage. However, the net benefits in the level of overall performance for insertion loss, isolation and linearity outweighs the disadvantages.

Abstract: The present disclosure generally relates to any device capable of wireless communication, such as a mobile telephone or wearable device, having one or more antennas. After measuring reflection coefficients of a device at three different DVC states, the reflection coefficient for all other DVC states can be calculated. Thus, based solely upon three reflection coefficient measurements, the antenna can be tuned to adjust for any changes in impedance at the antenna.

Abstract: The present disclosure generally relates to any device capable of wireless communication, such as a mobile telephone or wearable device, having one or more antennas. By applying a variable reactance (capacitive or inductive component) antenna aperture tuner within a simple, scalar antenna aperture tuning system, the maintenance of a constant antenna resonant frequency in the presence of environmental changes or head/hand effects is obtained. The variable reactance is used to adjust the resonant frequency of the antenna to stay at the desired target frequency in response to external variables that would otherwise shift the resonance away from the operating frequency of the device. Adjusting the resonant frequency of the antenna in response to externally induced changes maintains the radiating efficiency of the antenna and simultaneously avoids impedance mismatch between the antenna and the respective transmit/receive path in the radio, thereby minimizing transmission losses.
