Characteristics of a compact CPW resonant cell

This paper proposes a novel structure called a compact coplanar waveguide resonant cell (CCRC), which can exhibit slow-wave and bandstop characteristics by only one single unit. The same pattern has been adopted in the compact microstrip resonant cell (CMRC) as reported previously and here is applied to CPW with both infinite and finite ground planes. Experimental results show quite good agreement with simulations. By alternating the slot width of the CCRC section from that of normal CPW, good transmitting characteristics can be achieved at a passband of law frequency. © 2003 Wiley Periodicals, Inc.
