Design of a Compact Quad-Channel Microstrip Diplexer for L and S Band Applications

Abstract: In this paper, two novel dual-band bandpass filters (BPFs) and a compact quad-channel diplexer working at 1.7/3.3 GHz and 1.9/3.6 GHz are proposed. In the proposed diplexer design, triangular loop resonators and rectangular loop resonators are used together to reduce the circuit size and improve diplexer performances. Insertion loss (IL) and return loss (RL) of the proposed diplexer are better than 0.8 dB and 21 dB, respectively, at these four operating frequencies. Output ports isolation parameter is better t… Show more

“…21 Lastly, LCD screens degrade rapidly at low wavelengths and are thus limited to >400 nm illumination, which reduces material selection and ink efficiency. 12, 20, 22, 23 Prior work has shown success in leveraging LCD 3D printing for microfluidic master mold fabrication, 2427 but the potential for throughput manufacturing on large build plates and direct LCD 3D printing of open and embedded microchannels has not been shown.…”

“…In [32], two dual-band filters (BPFs) are used to create a quad channel, but insertion losses at operating bands are high. In [32][33][34], neural network models are used to obtain the desired values of parameters in microwave devices, which resulted in optimum performances.…”
