“…For simplicity and compactness, the diplexer was made using a common junction rather than the traditionally used external connection for energy distribution. The use of microstrip structures with a huge relative dielectric constant of 80 and no short-circuited elements [13] allows for the development of diplexers using two-and three-resonator microstrip structures. With frequency-contiguous channels for the differential mode and strong common-mode rejection, a new type of balanced dualband planar diplexer was projected in [14].…”

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.

“…A common junction was utilized to produce the diplexer employing an exterior junction for the energy allocation in the diplexer that usually raises the complication of the design and results in a huge equipment. The ability to develop diplexers by combining two and three resonator microstrip models, which are created with the elevated relative dielectric constant ε r = 80 without short-circuited elements, is achieved in [13]. In [14], the authors proposed a diplexer with dual-channel utilizing microstrip open loop coupled resonators, where each of them has dual working band frequencies.…”

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.
