In this paper, a new design of the advanced elliptic function RF/microwave filter is presented. This filter is designed with compact size using novel miniaturized resonators. This new type of filter includes zero order characteristic with double spiral resonator. The resonator shows sharp cut-off frequency response and possibility of size reduction. The elliptic function filter with only a pair of...
In this paper, integration of bandstop filter with the flexible narrow bandwidth of bandpass filter with lambdag/2 open stubs by microstrip line on duroid substrate is presented. This kind of filter shows flexible bandwidth with variation of the position of the open stubs using the external quality factor, Qe without changing the impedance value at microwave range. On the other hand, by replacing...
