Abstract
The present disclosure provides a low-cost beam scanning antenna and method of beam scanning in which two phase shifts are performed in an array of antenna elements. One of the phase shifts is performed in discrete stepwise increments in a feedline of the antenna element and another phase shift is performed by radiating a signal through variable phase shifters. The amount of phase shift provided by the variable phase shifters is varied by changing a rotation angle of the variable phase shifters.
Claims8
A beam scanning antenna, comprising:
- at least one linear array element, each linear array element having
- at least one patch antenna, each patch antenna including
- a feed line,
- a radiating element configured to radiate a signal from the feed line,
- a phase shifting device configured to provide a first phase shift in the feed line, and
- a precision rotary device;
- and
- at least one metasurface-based superstrate positioned above the respective patch antenna and configured to introduce a second phase shift in the signal traversing therethrough;
- wherein the second phase shift varies due to rotation of the at least one metasurface-based superstrate by the precision rotary device.
