Compact dual-band implantable antenna for e-health monitoring
Sajjad, Hassan; Sethi, Waleed Tariq; Khan, Sana; Jan, Latif (Institute of Electrical and Electronics Engineers, 2017)This work presents a compact dual-band Planar Inverted F-antenna (PIFA) antenna useful for E-health monitoring and wireless sensors systems. The antenna operates in the Industrial Standard and Medical (ISM) and Wireless ... -
A compact hairpin filter with stepped hairpin defected ground structure
Sajjad, Hassan; Altaf, Ahsan; Khan, Sana; Jan, Latif (Institute of Electrical and Electronics Engineers Inc., 2018)A compact hairpin line bandpass filter is presented with two different defected ground structures (DGS). The DGS are used to reduce the distributive response of the microstrip filter. The harmonic at 2 fo is suppressed to ... -
Compensation for the mutual coupling in transmitting antenna arrays
Khan, Sana; Arvas, Ercüment (Institute of Electrical and Electronics Engineers Inc., 2016)A numerical study is presented for the compensation of mutual coupling in antenna arrays. A Matlab code based on method of moments is used to find the compensated far field radiation patterns for non-identical and/or ... -
ISM band 1:16 wilkinson power divider
Altaf, Ahsan; Sajjad, Hassan; Khan, Sana; Munir, Mehre (Institute of Electrical and Electronics Engineers Inc., 2018)A 1:16 Wilkinson power divider (WPD) working from 1.3 GHz to 3 GHz is presented in this paper. Equal power division, phase and amplitude consistency is achieved among the output ports. The proposed design has a wideband ... -
Microwave heating of heavy oil and bitumen
Arvas, Serhend; Sajjad, Hassan; Altaf, Ahsan; Khan, Sana; Arvas, Ercüment (Institute of Electrical and Electronics Engineers Inc., 2016)A theoretical study is presented for the feasibility of a microwave heating device that will raise the temperature of heavy oil and bitumen reservoir. The device is enclosed in a radome which is surrounded by a perforated ... -
Mutual coupling compensation in receiving antenna arrays
Khan, Sana; Sajjad, Hassan; Özdemir, Mehmet Kemal; Arvas, Ercüment (Institute of Electrical and Electronics Engineers Inc., 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 (Institute of Electrical and Electronics Engineers Inc., 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 reduction in array elements using EBG structures
Sajjad, Hassan; Khan, Sana; Arvas, Ercüment (Institute of Electrical and Electronics Engineers, 2017)A 2D electromagnetic band gap (EBG) structure is designed on the ground plane of 1×2 rectangular patch antenna array to reduce the mutual coupling between the two elements and enhance the radiation pattern. An isolation ...
