Abstract :
A novel coupled-line hairpin unit is proposed to design a compact bandstop filter. In order to improve the performance of the filter, defected microstrip structure is used in the parallel coupled line section. Design equations are obtained using a lossless transmission line model and parallel coupled line model. To validate the analysis, a bandstop filter with about 67% fractional bandwidth at 5 GHz has been fabricated. The implementation area is 0.241λg × 0.068λg .
