Zusammenfassung:ABSTRACT A compact planar elliptic function lowpass filter with sharp roll‐off at 20 dB attenuation level and wide stopband using microstrip stepped‐impedance polygonal patch resonators is developed and investigated. Electromagnetic simulation is used to optimize the performance of the filter. The filter using cascaded multiple patch resonators provides a very sharp attenuation near cutoff frequency with a high stopband suppression level. The rejection bandwidth is enhanced by introducing additional transmission zeroes and the results are validated by the experiment. The filter has a compact size of 17.6 mm × 12.2 mm. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:133–136, 2016
