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.
