ANTENNA AND METHOD FOR STEERING ANTENNA BEAM DIRECTION FOR WIFI APPLICATIONS

摘要

An antenna comprising an IMD element and one or more parasitic and active tuning elements is disclosed. The IMD element, when used in combination with the active tuning and parasitic elements, allows antenna operation at multiple resonant frequencies. In addition, the direction of antenna radiation pattern may be arbitrarily rotated in accordance with the parasitic and active tuning elements. Unique antenna architectures for beam steering in Wi-Fi band applications is further described.

1. An antenna assembly, comprising:
a radiating element positioned above a ground plane forming an antenna volume therebetween; one or more parasitic elements positioned adjacent to the radiating element and outside of the antenna volume; and at least one of:
an active component configured to couple one of the parasitic elements to said ground plane,an active module configured to couple one of the parasitic elements to said ground plane, ora combination thereof; wherein the antenna assembly is configured with one or more resonances, said resonances including one or more resonances in the 2.4 GHz band, one or more resonances in the 5 GHz band, or a combination thereof.
