  • A novel, simple and broadband $180^{\circ}$ bit X-band phase shifter was proposed and fabricated in a standard micromachining process. It is composed of two $90^{\circ}$ parallel-coupled lines; one of which is shorted and the other is grounded. Design equations for the proposed $180^{\circ}$ bit phase shifter are derived by the method of even and odd mode analysis. Based on design equations, $180^{\circ}$ bit phase shifter was designed and fabricated to operate from 7 to 13 GHz with ${\pm}5^{\circ}$ of phase deviation.
