A Compact Filtering Coupler with Unwanted Harmonic Rejection Using LC Composite Lines for Communication Systems Applications
(MDPI, 2023)
In this paper, new LC lumped components and composite lines are used to create a filtering branch line coupler (FBLC) with a small size and wide suppression band. New composite lines are proposed using applied LC lumped ...
A Cross-Layer Solution for Contention Control to Enhance TCP Performance in Wireless Ad-hoc Networks
(Institute of Electrical and Electronics Engineers Inc., 2023)
With the development of wireless technology, users not only have wireless access to the Internet, but this has also sparked the emergence of Wireless Ad-hoc Networks (WANETs); this promising networking paradigm has the ...

(MDPI, 2023)
This study investigates the impact of factors (network coverage, customer service, video calls, and downloading Speed) of 3G and 4G telecommunication services performance on customer satisfaction in the Punjab region of ...
Mutual Coupling Reduction in Antenna Arrays Using Artificial Intelligence Approach and Inverse Neural Network Surrogates
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
This paper presents a novel approach to reducing undesirable coupling in antenna arrays using custom-designed resonators and inverse surrogate modeling. To illustrate the concept, two standard patch antenna cells with 0.07λ ...
A Compact Microwave Quadrature Hybrid Coupler Using Capacitive Composite Lines and Meandered Stubs
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-12)
In this paper, a new structure of the quadrature hybrid coupler (QHC) with compact size is proposed using capacitive composite lines and meandered open stubs. The proposed coupler works at 1.6 GHz with a 0.4 GHz bandwidth, ...
