A microstrip phase shifter design using a switch-loaded ground plate

Dowon Kim, Moonil Kim

Research output: Contribution to journalArticlepeer-review


A microstrip phase shifter design that uses a reconfigurable metal pattern on the EBG ground plate is introduced. The EBG ground plate metal pattern contains a linear array of thin slots with switching devices loaded at the center. This design can vary the phase constant with minimum mismatch loss over a large frequency bandwidth. Several test ground plates without actual switching devices were used to verify the design concept.
