CPW

Designs based on Yu-Kang Kuo, Chi-Hsueh Wang, Chun Hsiung Chen, Novel Reduced-Size Coplanar Waveguide Bandpass Filters. IEEE Microwave and Wireless Components Letters, Vol. 11, No. 2, Feb. 2001
Wideband and narrowband finite ground coplanar waveguide (FGCPW) filter analysis by Sonnet Professional. Narrowband design shows a package-induced resonance at 3.46 GHz unanticipated by conventional filter design techniques.
