چکیده
|
In this paper, chiral e-shaped resonators are used in a waveguide. direction of em wave and position of resonators for effective excitation is studied and various resonances of e-shaped resonators are determined. as a consequence an analytical equivalent circuit model is proposed. finally, an array of these resonators is used to realize a wide reject band. the resulted band stop filter performance is simulated and a rejection level of almost 40 db is achieved to confirm the effectiveness of the idea. this stopband filter is used in cascade with a bandpass filter to suppress its spurious response.
