“…Transition band is 0.29 GHz; 3 dB cut-off frequency is 1.46 GHz. Rohde & Schwarz ZVL20 Network Analyzer microstrip diplexer that has minimal insertion loss, good selectivity, and excellent isolation has been proposed in [22]. With fractional bandwidths of 2.8% and 3.2%, the structure offers good insertion losses for the two channels of about 1.6 and 1.3 dB respectively.…”

“…T-junction impedance matching networks have seen extensive use in diplexers as a three-port matching network. Though massive in scale, the T-dimension junctions must be chosen with care [22]. In cases where the number of multiplexer channels is greater than 2, however, the design of a matching circuit can be challenging [45].…”

This paper presents the design of microstrip-based multiplexers using stub-loaded coupled-line resonators. The proposed multiplexers consist of a diplexer and a triplexer, meticulously engineered to operate at specific frequency bands relevant to IoT systems: 2.55 GHz, 3.94 GHz, and 5.75 GHz. To enhance isolation and selectivity between the two passband regions, the diplexer incorporates five transmission poles (TPs) within its design. Similarly, the triplexer filter employs seven transmission poles to attain the desired performance across all three passbands. A comprehensive comparison was conducted against previously reported designs, considering crucial parameters such as size, insertion loss, return loss, and isolation between the two frequency bands. The fabrication of the diplexer and triplexer was carried out on a compact Rogers Duroid 5880 substrate. The experimental results demonstrate an exceptional performance, with the diplexer exhibiting a low insertion loss of 0.3 dB at 2.55 GHz and 0.4 dB at 3.94 GHz. The triplexer exhibits an insertion loss of 0.3 dB at 2.55 GHz, 0.37 dB at 3.94 GHz, and 0.2 dB at 5.75 GHz. The measured performance of the fabricated diplexer and triplexer aligns well with the simulated results, validating their effectiveness in meeting the desired specifications.
