Analysis of a compact multi-band textile antenna for WBAN and WLAN applications
Savcı, Hüseyin Şerif; Sajjad, Hassan; Kaburcuk, Fatih; Khan, Sana (Istanbul Technical University, 2021)A dual-band wearable antenna is designed on a textile material. The design operates at ISM bands available for Wireless Body Area Network (WBAN) and Wireless Local Area Network (WLAN) with an input match better than -15 ... -
Mutual coupling compensation in receiving antenna arrays
Khan, Sana; Sajjad, Hassan; Özdemir, Mehmet Kemal; Arvas, Ercüment (Applied Computational Electromagnetics Society (ACES), 2020)Mutual coupling compensation in uniform linear and circular receiving antenna arrays of thin wire dipoles is presented. It was observed that the mutual impedance is independent of the incident angle and depends solely on ... -
Mutual coupling compensation in receiving arrays and its implementation on software defined radios
Khan, Sana; Sajjad, Hassan; Özdemir, Mehmet Kemal; Arvas, Ercüment (Applied Computational Electromagnetics Society, 2020)Mutual coupling is compensated in a four element uniform linear receiving array using software defined radios. Direction of arrival (DoA) is estimated in real-time for the array with spacing d=lambda/4. The decoupling ... -
Mutual coupling compensation in transmitting arrays of thin wire antennas
Khan, Sana; Sajjad, Hassan; Özdemir, Mehmet Kemal; Arvas, Ercüment (Applied Computational Electromagnetics Society (ACES), 2018)This paper presents a numerical technique for the compensation of mutual coupling in transmitting arrays of thin wire antennas. The Method of Moments is used to compute the scattering parameters of the array. Using these ... -
Scattering by a chiral cylinder of arbitrary cross section above a dielectric half-space
Sajjad, Hassan; Altaf, Ahsan; Özzaim, Cengiz; Arvas, Ercüment (Institute of Electrical and Electronics Engineers Inc., 2021)A simple numerical solution for electromagnetic scattering from a 2-D homogeneous chiral cylinder of arbitrary cross section placed above a dielectric half-space (DHS) is presented. A modified surface equivalence principle ... -
Scattering from chiral cylinders of arbitrary cross-sections above a ground plane
Altaf, Ahsan; Sajjad, Hassan; Özzaim, Cengiz; Arvas, Ercüment (IEEE-Institute of Electrical and Electronics Engineers Inc, 2021)The main purpose of this work is to solve the problem of electromagnetic scattering from a chiral cylinder of arbitrary cross-section above an infinite perfect electric conducting (PEC) plane. Using image theory, this ...
