A narrow‐bandwidth dual‐band (DB) band‐pass filter (BPF) with λg/2 open stubs constructed using composite right/left‐handed (CRLH) metamaterial transmission lines (TLs) is presented. A conventional narrow BPF with λg/2 open stubs is first designed using series λg/2 open stubs and λg/4 TLs. Then, a DB filter can then be easily implemented by replacing the microstrip lines with the CRLH‐TL unit cells...
In this paper, a narrow bandwidth dual-band (DB) band-pass filter (BPR) with λg/2 open stubs using composite right/left-handed (CRLH) meta-material transmission lines is presented. A conventional narrow BPF with λg/2 open stubs is first designed using series λg/2 open stubs and λg/4 transmission lines. Then, a DB filter can then be easily implemented by replacing the microstrip lines with the CRLH...
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...
