Abstract: Miniaturized microstrip bandpass filters using novel resonator structures are presented. Firstly, a new class of compact microstrip filter loaded with low characteristic impedance triangular stub is introduced. The filter upper stopband selectivity is improved. Frequency tuning can be achieved by adjusting the reactance of the stub. Secondly, microstrip square open-loop resonator loaded with interdigital capacitive fingers is also proposed. Filters of this type with elliptic function and Chebyshev response are demonstrated. The advantage of the filter presented here not only features smaller in size but also has a wide upper stopband. There is good agreement between experiment and full-wave electromagnetic (EM) simulation results.
