Abstract :
A new approach to realizing the miniaturized coplanar waveguide dual-band filter has been proposed. Embedding the spiral coupled line into the lowpass filter, the filter can readily generate dual passbands. The center frequencies of two passabands are designed at 2.4 and 5.8 GHz. The corresponding design equations have been described under ideal lossless conditions. Moreover, this coupler can be fabricated using a standard printed circuit board process, of which being easily applicable to the design of microwave or millimeter-wave integrated circuits.
