In this article, a new type of microstrip vias-free balanced-to-balanced diplexer suitable for narrow-band applications is presented. The structure of the balanced diplexer is based on two balanced bandpass filters designed for f151.1 GHz and f251.8 GHz and two transmission lines used to satisfy the open circuit conditions required in the diplexer’s design. This diplexer exhibits good common-mo...

This paper presents the procedure for designing a waveguide E-plane diplexer for Ku band with inserted metal septa. The diplexer is designed with filters of the fifth order and with T-junction in E-plane for the purpose of easier integration with microwave transceiver. The aim of this work is to master the design of a diplexer that should obtain 60 dB insulation between receiver and transmitter...

This study proposed a novel methodology for designing bandpass multiplexer-integrated power dividers (PDs) that provide frequency division, selection, and division. New coupling schemes the PDs were presented to ensure multifunctionality compactness. Miniaturization was achieved through common resonator technique. Dual-mode stub-loaded resonators serving as various channel passbands used in PD ...

A two-dimensional photonic crystal diplexer integrated with a waveguide coupler is proposed. The design is computer generated through an inverse design process, limited within an area measuring 5 mumx5 mum. The best working device was designed for the optical communication wavelengths, 1.50 mum and 1.55 mum, i.e. a channel spacing of 50 nm. The device exhibits crosstalks suppressed below 40dB a...

─ A simple and novel low-loss diplexer with two folded Open-Loop Ring Resonators (OLRRs) that couple three microstrip lines is proposed. The first passband and second passband of the designed diplexer could be easily and accurately shifted to a desired frequency and construct the bandpass filters by adjusting the physical dimensions of the OLRRs. These results suggested that the proposed diplex...

In this paper, a compact microstrip diplexer is proposed for Wimax and DCS applications at 2.5 GHz and 1710-1880 MHz respectively. The microstrip diplexer consists of two band-pass filters operating at different frequency bands and a coupledjunction. Each filter is formed by a meander-line resonator and two Input/Output feed lines. The frequency response of each filter can be easily controlled ...

Symmetry is essential in the design of complex systems like Metaverse Transportation Sys-tem (MTS) and helps ensure that all components work together effectively. In development a microstrip diplexer for 5G-enabled IoT MTS, maintaining symmetry crucial to achieving flat responses with low group delays. By integrating transportation technology Metaverse, System can greatly improve effectiveness ...
