Design and Analysis of a Compact GSM/GPS Dual-Band Bandpass Filter Using a T-Shaped Resonator
Basit, Abdul; Khattak, Muhammad Irfan; Al-Hasan, Mauth; Nebhen, Jamel; Jan, Atif (Korean Institute of Electromagnetic Engineering and Science, 2022)This study presents an ultracompact dual-band bandpass filter with controllable transmission zeros based on quarter-wave dual-mode resonator for GSM (global system for mobile communications) and GPS (global positioning ... -
A frequency and radiation pattern combo-reconfigurable novel antenna for 5g applications and beyond
Shereen, Muhammad Kamran; Khattak, Muhammad Irfan; Al-Hasan, Mu’ath (MDPI AG., 2020)This paper presents a novel combo-reconfigurable architecture for the frequency and radiation patterning of a novel antenna system for future fifth-generation (5G) millimeter-wave mobile communication. The tuning system ... -
Miniaturized MIMO Antenna with Low Inter-radiator Transmittance and Band Rejection Features
Khan, Muhammad Irshad; Khattak, Muhammad Irfan; Al-Hasan, Mauth (Korean Institute of Electromagnetic Engineering and Science, 2021)In this article, compact a multiple-input and multiple-output (MIMO) system with flag-shaped radiators and a mountain-shaped ground plane is presented. Isolation is enhanced with the help of a decoupling stub placed between ... -
On Learning Spectral Masking for Single Channel Speech Enhancement Using Feedforward and Recurrent Neural Networks
Saleem, Nasir; Khattak, Muhammad Irfan; Al-Hasan, Muath; Qazi, Abdul Baseer (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 ...
