Abstract :
A novel defected ground structure cell was presented. The cell was built on coplanar waveguide technology. Two diodes in each side of the ground planes allow us to switch the filter between different passbands. Simulated and measured responses were presented showing very good agreement. An electromagnetic explanation of the structure based on slot transmission line was also presented. The cell shows very promising features for the implementation of small and efficiently reconfigurable building block for filters. The very narrow stopbands in the responses may be enhanced by putting more cells in cascade. This work is a first step toward implementation of a silicon integrated reconfigurable filter using MEMS switches in place of diodes.
