Abstract
In this paper, the design concept and implementation method of the X-band 4-bit($22.5^{\circ}$, $45^{\circ}$, $90^{\circ}$, $180^{\circ}$ BIT) diode phase shifter in the parallel plate waveguide are introduced. The simulated results of $11.25^{\circ}$, $22.5^{\circ}$ and $45^{\circ}$ dielectric phase shift layers using CST's MWS and Agilent's ADS are presented, and the measured results are compared with the simulated ones. The simulated phase shift errors at the center frequency are $0.6^{\circ}$, $0.7^{\circ}$, and $3.5^{\circ}$, respectively and the measured phase shift errors at the center frequency are $0.6^{\circ}$, $2^{\circ}$, and $5.5^{\circ}$, respectively. Also, the MWS simulated results of $22.5^{\circ}$ BIT and $45^{\circ}$ BIT phase shifter are presented and compared with the ADS simulated ones to verify the validity of the presented design concept and implementation method.
