Abstract: A microstrip bandstop filter using four square air holes resonator at frequencies above 10 GHz has been investigated. The square air holes resonator generate a bandgap, and its operation mechanism is made clearly through the Finite Differential Time-Domain method. The measured frequency response of the filter is in good agreement with the simulation, and the center frequency of stopband of the microstrip filter shifted to higher frequency along with the dimension of the square air holes increased. © 2007 Wiley Periodicals, Inc.
