“…The developed miniaturized microstrip diplexer using FR4 substrate in this paper has been compared with developed microstrip diplexers in [11], [16]- [20] as explained by Table I. The superiority of the proposed diplexer mostly comes from the high compactness, excellent return loss values, and the highest band isolation as compared with the reported diplexers in [11], [16]- [20]. The minor tolerable disadvantage of the designed device is that it has an insertion loss of 4.2 dB for channel 1 and 3.3 dB for channel 2, that are attributable to the dielectric loss and are comparable to the diplexer reported in [22].…”

“…The simulation and measurement have verified the projected diplexer. In [11], a novel microstrip diplexer employing H-shaped resonators with small dimensions and elevated band isolation has been introduced. This design has been operated under 2.4 GHz for the Industrial Scientific Medical (ISM) application, and under 1.575 GHz, for the GPS application.…”

In this paper, the miniaturized microstrip diplexer has been designed for dual channels based on FR4 substrate material. It consists of two bandpass filters (BPFs) functioning under dissimilar frequency bands coupled with a unified junction. Every BPF has been created by a meandered line resonator, step impedance resonator, uniform impedance resonator, and input/output feed lines. The AWR electromagnetic simulator has been used for characterizing the frequency responses of the projected diplexer. Noble scattering parameter results with narrow band responses and negative group delay values are obtained for the proposed diplexer. The microstrip diplexer has an interesting band isolation between the two filters around 31 dB. The device has been successfully fabricated and verified with the simulations.

“…The interesting consistency between the simulation and measurement data validates the design process. In [11], the authors presented a microstrip diplexer that uses modernized H-shaped resonators to achieve small size and sound band isolation. This layout is compatible with the ISM (2.4 GHz) band and the GPS (1.575 GHz) frequencies.…”

Using Kappa substrate material, a compact microstrip diplexer is developed in this research with two separate channels based on the coupled junction and two bandpass filters functioning in independent frequency bands. Each filter comprises an input/output feed line and a number of resonators with different impedances. The diplexer’s frequency response was modeled and optimized using the Sonnet EM solver. At 2.84 and 4.08 GHz for TX/RX channels, the insertion loss is better than 1 dB for both channels, while the return loss values are 21.2 and 17 dB for transmit and receive filters, respectively. The microstrip diplexer has miniature dimensions of 24 mm × 18 mm with highly narrow bands and band isolation of more than 35 dB. The simulated scattering parameters are in agreement with the measured ones.

“…[13] introduces a novel microstrip model for designing bandpass filters using coupled stepped impedance resonators, augmenting the arsenal of design methodologies. In [14], a unique microstrip diplexer harnessing H-shaped resonators with compact dimensions and exceptional band isolation is presented, targeting applications in the industrial scientific medical (ISM) and GPS frequency bands. Addressing the perennial challenge of matching schemes, works such as [15][16][17][18] proffer systematic approaches, albeit necessitating supplemental matching circuits outside of the filters, often involving additional lumped components.…”

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.
