“…Figure 6 shows the current density distribution of the proposed triplexer for simulating ports 2, 3, and 4 at 0.815 GHz, 1.58 GHz, and 2.65 GHz, respectively. As shown in Figure 5 , the wide sections (low-impedance sections) have lower current density [ 34 ]. According to the information obtained from the current density distribution, we can find the more effective lengths and widths for optimizing.…”

Global concerns regarding environmental preservation and energy sustainability have emerged due to the various impacts of constantly increasing energy demands and climate changes. With advancements in smart grid, edge computing, and Metaverse-based technologies, it has become apparent that conventional private power networks are insufficient to meet the demanding requirements of industrial applications. The unique capabilities of 5G, such as numerous connections, high reliability, low latency, and large bandwidth, make it an excellent choice for smart grid services. The 5G network industry will heavily rely on the Internet of Things (IoT) to progress, which will act as a catalyst for the development of the future smart grid. This comprehensive platform will not only include communication infrastructure for smart grid edge computing, but also Metaverse platforms. Therefore, optimizing the IoT is crucial to achieve a sustainable edge computing network. This paper presents the design, fabrication, and evaluation of a super-efficient GSM triplexer for 5G-enabled IoT in sustainable smart grid edge computing and the Metaverse. This component is intended to operate at 0.815/1.58/2.65 GHz for 5G applications. The physical layout of our triplexer is new, and it is presented for the first time in this work. The overall size of our triplexer is only 0.007 λg2, which is the smallest compared to the previous works. The proposed triplexer has very low insertion losses of 0.12 dB, 0.09 dB, and 0.42 dB at the first, second, and third channels, respectively. We achieved the minimum insertion losses compared to previous triplexers. Additionally, the common port return losses (RLs) were better than 26 dB at all channels.

“…Another feature of MRS is that it can be used for adjustable cancellation. 40 Other techniques used to increase sensitivity are including ratrace coupled, 41 parallel coupled, 42 phase variation, 43 GaAs monolithic microwave IC, spiral band-gap, nearfield self-injection-locked, 44 and coplanar waveguide-fed wearable antenna. [45][46][47][48][49] The introduced technique can also be used in optical sensors 50 such sensors of plasmon or graphene-based.…”

In this manuscript, a microwave resonance sensor (MRS) was presented composed of interdigital structure, meander structure, chandelier‐form, and T‐shaped structure. The combination of four structures results in a good electromagnetic field strength at the sensing location. It caused increased sensitivity. Due to the high use of methanol in industry, samples have been selected from this material. The samples used are methanol and water solution and place on location sensing. For measurement was used samples with 80% methanol with a permittivity of 59%–10% methanol with a permittivity of 77. Also, tissue samples including sheep, chicken and fish have been used to measure the proposed sensor. The resonance frequency of the samples changes in the range of 2.14‐1.46 GHz. The sensitivity of the presented MRS is 2.6% and the Q‐factor is 1252.
