This patent discloses a broadband high pass microwave filter and method of manufacturing thereof that maximizes the frequency separation between the desired passband of the filter and spurious passbands. A strip of dielectric material has alternately spaced capacitor plates formed on both sides thereof such that parallel plate capacitors are formed at the overlapping sections of the capacitor plates. The dielectric strip is folded in accordian-like fashion and inductive leads are electrically connected to the capacitor plates at each of the folds. The folded dielectric strip is mounted on an MIC substrate, the end plates of the strip are electrically connected to microstrip conductors on the substrate and the inductive leads are connected to the ground plane of the microstrip substrate to thereby form the high pass microwave filter.
