A nested square-shape dielectric resonator for microwave band antenna applications
(Institute of Advanced Engineering and Science, 2021)
In this paper, a nested square-shape dielectric resonator (NSDR) has been designed and investigated for antenna applications in the microwave band. A solid square dielectric resonator (SSDR) was modified systematically by ...
Design and analysis of a microstrip planar UWB bandpass filter with triple notch bands for WiMAX, WLAN, and X-Band satellite communication systems
(Electromagnetics Academy, 2020)
This manuscript presents a UWB filter with three notch bands for WiMAX, WLAN, and X-Band Satellite Communication by introducing inverted E-and T-shape resonators shorted at the center, designed and fabricated for the use ...
Expedited Yield Optimization of Narrow-and Multi-Band Antennas Using Performance-Driven Surrogates
(Institute of Electrical and Electronics Engineers Inc., 2020)
Uncertainty quantification is an important aspect of engineering design, also pertaining to the development and performance evaluation of antenna systems. Manufacturing tolerances as well as other types of uncertainties, ...
Design-Oriented Two-Stage Surrogate Modeling of Miniaturized Microstrip Circuits with Dimensionality Reduction
(Institute of Electrical and Electronics Engineers Inc., 2020)
Contemporary microwave design heavily relies on full-wave electromagnetic (EM) simulation tools. This is especially the case for miniaturized devices where EM cross-coupling effects cannot be adequately accounted for using ...
Cost-Efficient Bi-Layer Modeling of Antenna Input Characteristics Using Gradient Kriging Surrogates
(Institute of Electrical and Electronics Engineers Inc., 2020)
Over the recent years, surrogate modeling has been playing an increasing role in the design
of antenna structures. The main incentive is to mitigate the issues related to high cost of electromagnetic
(EM)-based procedures. ...
On Learning Spectral Masking for Single Channel Speech Enhancement Using Feedforward and Recurrent Neural Networks
(Institute of Electrical and Electronics Engineers Inc., 2020)
Human speech in real-world environments is typically degraded by the background noise.
They have a negative impact on perceptual speech quality and intelligibility which causes performance
degradation in various ...
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 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 ...
Implementation of Spatial/Polarization Diversity for Improved-Performance Circularly Polarized Multiple-Input-Multiple-Output Ultra-Wideband Antenna
(IEEE, 2020)
In this paper, spatial and polarization diversities are simultaneously implemented in an ultra-wideband (UWB) multiple-input-multiple-output (MIMO) antenna to reduce the correlation between the parallel-placed radiators. ...
