“…Dual/triple-narrowband bandpass filters (BPF) are one of the most popular components increasingly investigated in the most recent studies. Many triple-band BPFs have been introduced by different topologies in several investigations: however, they still occupy a relatively large area on their substrates and often with complicated structures [1][2][3][4][5][6][7][8][9][10]. For instance, a triple-band BPF has been proposed in [3] using asymmetric coupled lines where it has been designed using multi-layered technology with a size about 64 × 38 mm 2 on its substrate.…”

In this paper, a compact triple-narrowband bandpass filter is designed and proposed using microstrip resonators . The proposed triple-band BPF consists of two half-wave resonators in combination with a simple anti-parallel coupled lines which realizes a triple-band BPF with a size reduction about 42% in comparison with the conventional one. Additionally, transmission zeroes of the proposed structure guarantee the sharpness the skirts of scattering parameters of triple-band BPF. The frequency response of the filter is simulated using an EM simulation tool.
