The design of compact suspended stripline (SSL) bandpass filters is demonstrated. Equivalent circuit models of lumped elements for the proposed filters are also developed to analyze the circuit behaviors. The SSL filters have achieved the benefits of size compactness, extremely low insertion losses, low dispersion, high operation frequency, and sometimes a wide stopband. Experiments are conducted to validate the SSL filters' performance.
