碩士 === 義守大學 === 電機工程學系碩士班 === 94 === The purpose of this thesis is to design bandgap filter by adopting the idea of microstripline and photonic bandgap. The one-dimension bandstop filter is mainly structured by the periodical changes of microstripline and planned from the models of step, triangle and sinusoidal. The software will be utilized to simulate different types and different pairs as the basis to observe the frequency response of one-dimension bandstop filter and as a comparison with the experiment. The bandstop filter with one-dimension triangle and one-dimension sinusoidal causes suppression of harmonic. Furthermore, in order to complete a coplanar two-dimension bandstop filter, this plan will reply on combination of divider and the bandstop filter with one-dimension triangle and one-dimension sinusoidal.
