摘要： Antennas of broadband and multi-band operation are presented. A broadband planar antenna includes two inverted-L antennas (ILAs) facing each other across a gap. One of the ILAs is input fed, and the other is electromagnetically coupled. The positioning of the gap affects the bandwidth. A dual-band planar antenna includes two ILAs facing each other across a gap with one of the ILAs being input fed, and the other being coupled. This dual-band planar antenna also includes a monopole antenna disposed between the two ILAs. A triple-band planar antenna includes two ILAs facing each other across a gap with one of the ILAs being input fed and the other IPA being coupled. This triple-band antenna also includes a monopole antenna disposed between the two ILAs, and a conductor extending horizontally from the monopole antenna towards, but not reaching the coupled ILA. Another dual-band antenna includes an inner cut loop antenna encompassed by an outer cut loop antenna. Each of the cut loop antennas includes two ILAs with one of the ILAs being input fed and the other being coupled.

摘要： A data transfer method for autonomous vehicles includes autonomously positioning a vehicle to achieve an alignment condition in which a vehicle-mounted directional antenna coupled to a vehicle radio is aligned with a curbside antenna coupled to a curbside radio. A peer-tip-peer radio link is established between the vehicle radio and the curbside radio, and data is transferred from the vehicle radio to the curbside radio using the peer-to-peer radio link. The peer-to-peer radio link may be a millimeter-wave radio link. Data is transferred at high speed, for example at least tens of gigabits per second or even hundreds of gigabits per second. The vehicle may be an electric vehicle, and electric charging of the vehicle may be performed while transferring the data. In one embodiment, the vehicle is configured to proceed to a recharging location when a given low state of charge is reached. Transferring data may be performed at a rate such that during recharging from the low state of charge to a target state of charge, all data to be transferred from the vehicle is transferred, or at least a terabyte of data is transferred.

摘要： Systems and methods for provided for linearization systems and methods for variable attenuators. The variable attenuators can include series transistors along a main signal path from the input to output, as well as shunt transistors. A bootstrapping body bias circuit can be used with one or of the series transistors to allow the body of a connected transistor to swing responsive to a received RF input signal. As the RF signal increases and affects the gate-to-source voltage difference of a transistor, a bootstrapping body bias circuit can adaptively adjust the threshold voltage of the connected transistor and compensate the channel resistance variation resulting from gate-to-source voltage swing. The bootstrapping body bias circuit can be implemented using passive elements, active elements, or a combination thereof.

摘要： Systems and methods for providing a self-mixing adaptive bias circuit that may include a mixer, low-pass filter or a phase shifter, and a bias feeding block. The self-mixing adaptive bias circuit may generate an adaptive bias signal depending on input signal power level. As the input power level goes up, the adaptive bias circuit increases the bias voltage or bias current such that the amplifier will save current consumption at low power operation levels and obtain better linearity at high power operation levels compared to conventional biasing techniques. Moreover, the adaptive bias output signal can be used to cancel the third-order intermodulation terms (IM3) to further enhance the linearity as a secondary effect.
