摘要:
The RF impedance of a metal trace at gigahertz frequencies is reduced by forming the metal trace to have a base region and a number of fingers that extend away from the base region. When formed to have a number of loops, the metal trace forms an inductor with an increased Q.

The radio frequency (RF) impedance of a metal trace at gigahertz frequencies is reduced by forming the metal trace to have a base region and a number of fins that extend away from the base region. When formed in a spiral configuration having a number of loops, the metal trace forms an inductor with an increased quality factor (Q).

A wireless tire pressure sensing system based upon a Schrader valve design is provided. The system includes a valve body, a valve pin and a compression element for sealing engaging the valve body and the valve pin to maintain tire pressure. A pressure sensing device mounted within the valve body and connected to valve pin senses the pressure within the tire and provides its signal to the valve pin. The valve pin is adapted as a component of an antenna that transmits a wireless pressure signal to a remote receiver/transmitter mounted on the vehicle. The receiver/transmitter transmits a corresponding signal to a vehicle control system that generates a warning signal when the tire pressure is below a threshold safety value.

A very, very low resistance micro-electromechanical system (MEMS) inductor, which provides resistance in the single-digit milliohm range, is formed by utilizing a single thick wide loop of metal formed around a magnetic core structure. The magnetic core structure, in turn, can utilize a laminated Ni—Fe structure that has an easy axis and a hard axis.
