Compact Right-Angled Coplanar Waveguide Using Central ShortCircuited Slotline

Abstract

- In this paper, a compact right-angled CPW using the central short-circuited slotline is proposed. The short-circuited slotline is fabricated on the central strip of the CPW so that it will not consume any additional area. As compared with the right-angled CPW using the short-circuited slotline [14], the reflection coefficient is maintained at a low value around -10 dB while the transmission coefficient is increased from -4.49 dB to -3.28 dB. Besides, the power loss is substantially reduced from 0.55 to 0.37.
