Phase Shifter Using an Artificial Magneto-Dielectric for Phase Array Antenna Application

초록

A phase shifter using artificial magneto-dielectric material for phase array antenna application is proposed. The miniaturization was achieved using an artificial magneto-dielectric, realized using a split ring resonator (SRR). By using superstrates with split-ring resonators (SRRs) on a T-junction power divider, a phase shift can be implemented over the Mobile-WiMAX band (2.3 GHz ~ 2.4 GHz) due to the high permeability property of the SRR. The SRR superstrate provides the low insertion loss and compact size for a phase shifter.
