Abstract This paper presents the design of a compact broadband coupler specifically dedicated to 5G applications. The innovative approach proposed skillfully merges two distinct methods: use stepped impedance structures and meanders. aim is not only miniaturize structure extend bandwidth, but also maintain high performance, particularly within 3.5 GHz core frequency band. effectiveness this reflected in remarkable reduction size, down by 59% compared with conventional designs. In addition,...
This paper presents a design and optimization approach for tri-band miniature planar rectangular patch antenna structure wireless mobile applications. The operation while maintaining compact size has been achieved by introducing defected ground (DGS) to control the surface current distribution on consequently achieve multi-band operation. geometry of position DGS were optimized genetic algorithm desired performance using simple with an area 16 mm × 20 1.6 mm, 82% reduction in occupied...
A compact hybrid patch coupler operating at 3.5 GHz for fifth generation applications is presented. By introducing cross-slots with T-shaped heads on the edges, proposed coupler’s overall size reduced significantly. The offers a reduction of 79% compared to occupied by conventional reference design. Simulation results show successful fit miniature such that reflection coefficient and isolation values are −44.27 dB −24.35 GHz. insertion coupling −3.18 −3.88 same resonance frequency, 30%...
This paper presents a compact rectangular patch hybrid coupler design which can be operated at dual resonant frequencies and is suitable for modern wireless applications. The dual-band functionality while maintaining practical compactness achieved by introducing series of parallel slots. proposed optimized the CST studio suite software etched on FR4 substrate. good agreement between simulated measured frequency responses indicate that presented capable operating from 2.44 GHz to 3.1 5 5.8...
The paper presents a new design of compact branch-line coupler (BLC) operating at 3.5 GHz, that is suitable for 5G applications. In order to miniaturize the proposed coupler, two miniaturization methods are combined where T-shaped structure used instead quarter wavelengths parallels, as well open stubs introduced into series lines resulting in size reduction 52.56% with 25.05% fractional bandwidth (FBW). frequency responses indicate presented able operate 3.04 GHz 3.91 low return loss and...
