摘要：
In this paper, a coplanar waveguide (CPW) fed continuous transverse stub (CTS) antenna array with beam steering capability is proposed and validated for cognitive radio applications. A novel reconfigurable negative reflect index (NRI) phase shifter is integrated with the CTS element to provide continuous phase states. The proposed phase shifter is based on CPW transmission line and consists of a series capacitor and two groups of shunt inductors. The continuous switching mechanism is achieved by adopting two groups of pin diodes and one varactor. A three-stage reconfigurable NRI phase shifters are integrated with the CPW-CTS antenna array, and a beam steering range of 81 degrees-107 degrees is achieved with stable gain.
