Abstract
A method for hybrid RF beamforming comprising: providing an antenna structure which comprises: a driven element, parasitic elements configured to couple/decouple a linearly polarized radiation pattern and arranged around the driven elements, a feed system comprising four ports that are 90 degrees out of phase with each other and are connected to the driven element, RF switches electrically connected to the parasitic elements and the four ports, and a controller operatively connected to the RF switches; selectively attenuating an output of each of the four ports with the controller according to a stored configuration, which is stored in a memory, by changing the four ports' respective phase or attenuation; and selectively changing a loading of each parasitic element by activating each parasitic element's corresponding RF switch with the controller according to the stored configuration so as to produce a desired null/beamforming of a main RF beam.
