A New Spoof Surface Plasma Polaritons Band-pass Filter with Interdigital Structure
A new type spoof surface plasma polaritons(SSPPs)band pass filter was devised successfully.The filter possessed three-section structure of composite groove,the co-planar wave guide as the first section,microstrip wave guide as the second section,and SSPPs as the third section.It should be noted that there is a interdigital structure or composite composite groove structure in the first or third section,which are carried out by the simulation on characteristics of upper drag band and bandwidth for band pass filter.These results indicated that the filter had bandwidth between 3.1504GHz and 6.3398GHz during-3dB-0dB,the ripple jitter in the passband being better than 0.8dB,and reflection being less than-10dB.This new type of SSPPs filter will be certain engineering value in the application of microstrip circuit,microwave base station and radar microwave communication system between L band and X band.
