Radio frequency antenna system and high-speed digital data link to reduce electromagnetic interference for wireless communications

Abstract

A radio frequency antenna system and high-speed digital data link are disclosed to, among other things, reduce electromagnetic interference ('EMI') at relatively high data rates while reducing the manufacturing complexities associated with conventional data links. In one embodiment, a radio frequency ('RF') antenna system includes an antenna and an RF radio coupled to the antenna for receiving wireless RF signals. In particular, the RF radio is configured to digitize RF signals at a fixed data rate to form digitized data signals and to apply the digitized data signals at a variable data rate to a high-speed digital link. The variable data rate distributes the signal energy of the digitized data signals over one or more bands of frequencies, thereby beneficially altering an EMI spectral profile describing emissions that develop as the digitized data signals are transported through a channel.
