Abstract
A low cost phase shifter is presented in this paper. It contains microstrip lines on one side of PCB backed with slot array on the ground plane. In addition, the moveable PCB having five metal strips serves as a phase shifter. By dynamically moving movable PCB, we can adjust the Number and shielding area of the slot array and then alter the distribution of phase angle at each port of the feeding network accordingly. The progressive phase between array elements is achieved by adjusting the line lengths of movable PCB. Simulations were conducted using ads software. Ease in fabrication, tilting mechanism, and low cost are the main reasons for choosing this type of phase shifting mechanism.
