Noise reducing near-field receiver antenna and system

Abstract

The present invention provides a noise reducing near-field antenna comprising a first and second antenna section and a digital signal processor. The first antenna section detects the magnetic field component of an incident signal and the second antenna section detects the electric field component of an incident signal. The first antenna section outputs a signal to the digital signal processor comprising a wanted magnetic field component of a near-field incident signal and a magnetic field component of an unwanted far-field noise signal. The second antenna section outputs the electric field component of the unwanted noise signal to the digital signal processor. The digital signal processor determines the magnetic field component of the unwanted incident signal from the electrical field component thereof and subtracts this value from the received signal of the first antenna section, thereby removing the unwanted noise signal from the near-field received signal.
