Title:
PHASE CONTROL FOR ANTENNA ARRAY
Document Type and Number:
WIPO Patent Application WO/2016/116066
Kind Code:
A1
Abstract:
Phase control apparatus and methods for antenna arrays are disclosed. Phase shifts at respective antenna element subunits along a first axis of an antenna array are controlled by applying a variable control voltage across a voltage divider to divide the variable control voltage into multiple voltages that are used to generate phase shift control voltages for phase shift elements corresponding to the respective antenna element subunits. The antenna array may be steered along the first axis by controlling the variable control voltage applied across the voltage divider. A second voltage divider could be used to extend phase control and steering to two dimensions.
