Filtering two-element waveguide antenna array based on solely resonators
Mahmud, Rashad H.; Awl, Halgurd N.; Abdulkarim, Yadgar I.; Karaaslan, Muharrem; Lancaster, Michael J. (Elsevier, 2020)This paper presents a design approach of a filtering antenna arrays based on the coupling matrix theory. The approach generates filtering functionality using the resonating array radiating elements and the resonator based ... -
Low-Cost Antenna-Array-Based Metamaterials for Non-Invasive Early-Stage Breast Tumor Detection in the Human Body
Hamza, Musa N.; Abdulkarim, Yadgar I.; Saeed, Salah Raza; Altıntaş, Olcay; Mahmud, Rashad H.; Appasani, Bhargav; Ravariu, Cristian (MDPI, 2022)Microstrip patch antennas have been used in many applications since their appearance. Despite their great promise, their narrow bandwidth and the loss at high-frequency bands have limited their usage in medical applications. ... -
A low-profile circularly polarized cavity-based waveguide aperture antenna
Mahmud, Rashad H.; Mohammed, Mustafa M.; Jarjees, Raad S.; Salih, Idris H.; Alkurt, Fatih Özkan; Karaaslan, Muharrem; Skaik, Talal (Wiley, 2024)This article proposes a new design of a circularly polarized (CP) aperture antenna based on a dual-mode rectangular waveguide cavity-resonator. A capacitive iris is employed to attain a strong coupling between the cavity ...
