Novel 5-bit Phase Shifter using CRLH Transmission Line with Interdigital Capacitor and Shorted Stubs
This paper presents a composite right-left hand (CRLH) transmission line (TL) inspired 5-bit digital phase shifter. The proposed phase shifter comprises three cascaded CRLH unit cells with overall eight PIN diodes are mounted on the horizontal and vertical outer fingers of the element. A systematic design approach is adopted to obtain phase shifts of 5.656,11.317,22.248,44.491, and 89.687 degrees with respect to a reference line at frequency 10 GHz. The proposed design possesses the advantages of low insertion loss $(\lt 2.16\mathrm{~dB})$ and return loss $\gt 12\mathrm{~dB}$ with high power handling capability over the frequency range of 9.9-10.1 GHz.
