Antenna system for interference supression

摘要

An antenna system is capable of optimizing communication link quality with one or multiple transceivers while suppressing one or multiple interference sources. The antenna provides a low cost, physically small multi-element antenna system capable of being integrated into mobile devices and designed to form nulls in the radiation pattern to reduce interference from unwanted interferers. The antenna system operates in both line of sight and high multi-path environments by adjusting the radiation pattern and sampling the received signal strength to reduce signal levels from interferers while monitoring and optimizing receive signal strength from desired sources.

1. An antenna system comprising:
a modal antenna comprising an antenna element positioned above a circuit board forming an antenna volume therebetween, one or more first parasitic elements positioned within said antenna volume, and one or more second parasitic elements positioned adjacent to said antenna and outside of said antenna volume, wherein each of said parasitic elements is coupled to an active element for actively configuring one or more modes of the antenna; and an antenna tuning module (ATM) adapted to provide control signals to the active elements for varying the one or more modes of the antenna.
