Improved-efficacy optimization of compact microwave passives by means of frequency-related regularization
(Institute of Electrical and Electronics Engineers Inc., 2020)
Electromagnetic (EM)-driven optimization is an important part of microwave design, especially
for miniaturized components where the cross-coupling effects in tightly arranged layouts make traditional
(e.g., equivalent ...
A 10-Ports MIMO Antenna System for 5G Smart-Phone Applications
(Institute of Electrical and Electronics Engineers Inc., 2020)
This paper presents a 10-ports hybrid multiple-input multiple-output (MIMO) antenna system for 5G Smartphone applications. The proposed antenna system comprises two types of antenna modules: (1) multi-band module consists ...
Analysis of multi-phase flow through porous media for imbibition phenomena by using the LeNN-WOA-NM algorithm
(Institute of Electrical and Electronics Engineers Inc., 2020)
The flow of fluids in multi-phase porous media results due to many interesting natural phenomena. The counter-current water imbibition phenomena, that occur during oil extraction through a cylindrical well is an interesting ...
An eigen-approach for joint estimation of direction-of-arrival and frequency of an unknown number of signals
(Scientific Research Support Fund of Jordan, 2020)
An accurate method for estimating the direction-of-arrival (DOA) jointly with the frequencies of an unknown number of source signals is proposed using the Eigen-approach. Using the minimum eigenvalues of the autocorrelation ...
A Systematic Design of a Compact Wideband Hybrid Directional Coupler Based on Printed RGW Technology
(Institute of Electrical and Electronics Engineers Inc., 2021)
Printed ridge gap waveguide (PRGW) is considered among the state of art guiding technologies due to its low signal distortion and low loss at Millimeter Wave (mmWave) spectrum, which motivates the research community to use ...
Correlation Reduction in Closely-Spaced MIMO Antenna with Circular Polarization Diversity
(Institute of Electrical and Electronics Engineers Inc., 2020)
Radiator correlation in multiple-input-multiple-output (MIMO) antenna has always been a serious concern for MIMO systems. In this paper, an antenna consisting of two parallel-placed coplanar waveguide (CPW)-fed radiators ...
A Comparison of Wireless Standards in IoT for Indoor Localization Using LoPy
(Institute of Electrical and Electronics Engineers Inc., 2021)
There are surplus applications in modern smart cities where localization of indoor environments is critical ranging from surveillance and trailing in smart structures to the localized wireless distribution of advertising ...
A novel lumped LC resonator antenna with air-substrate for 5G mobile terminals
(Electromagnetics Academy, 2020)
The extending applications for mobile computing have experienced immense progress over
the previous decade. However, this has ultimately influenced the shortage of bandwidth. Therefore,
to fulfill the consumers’ demand, ...
