In this article, the reduced size of the ultra‐wide band (UWB) band‐pass filter (BPF) with λg/4 short stubs using π‐type meander structure and folding short stubs is presented. The π‐type meander structure and folding short stubs are adopted instead of the λg/4 transmission line (TL) and λg/4 short stubs to reduce the size of the proposed BPF. The overall size of the new BPF is reduced by 72.5% over...
In this paper, the proposed band stop filter (BSF) with wide stop-band band using open stub using T-shaped stepped impedance resonator (SIR) is demonstrated. Then, the shunted open stub is connected to SIR part in which low impedance structure. The, SIR and shunted open stub has low insertion loss and wide bandwidth performance. At the same time, the unbalance quad-band BSF with L-shaped open stub...
