Journal ArticleDOI
Optically Transparent Flexible Robust Circularly Polarized Antenna for UHF RFID Tags
Abu Sadat Md. Sayem,Duc Le,Roy B. V. B. Simorangkir,Toni Bjorninen,Karu P. Esselle,Raheel M. Hashmi,Maxim Zhadobov +6 more
TL;DR: In this paper, an optically transparent and flexible radio frequency identification passive tag antenna operating in the ultra high frequency band and exhibits circular polarization is presented, which is thin, lightweight, and completely encapsulated inside transparent polymer, which protects it against dust, water, heat, and mechanical stress.
Journal ArticleDOI
Enhancing the performance of EBG resonator antennas by individually truncating the superstructure layers
Raheel M. Hashmi,Karu P. Esselle +1 more
TL;DR: In this article, the role of superstructure finiteness in improving the peak directivity and the directivity bandwidth of electromagnetic band gap (EBG) resonator antennas was studied.
Journal ArticleDOI
Experimental studies of the robustness of the conductive-mesh-polymer composite towards the development of conformal and transparent antennas
TL;DR: In this paper, the authors proposed a conductive mesh-polysiloxane (PDMS) composite material for flexible and optically transparent antennas, which is a flexible transparent substrate and a transparent conductor is mesh-structured flexible conductive textile.
Journal ArticleDOI
Millimeter-Wave Broadband Antennas With Low Profile Dielectric Covers
TL;DR: It is demonstrated that the entire unlicensed 60 GHz frequency band can be covered using a dielectric based aperture type antenna, which is unprecedented relative to medium-to-high gain millimeter-wave printed antenna arrays, used for similar applications.
Proceedings ArticleDOI
Improved Secure Network Authentication Protocol (ISNAP) for IEEE 802.16
Raheel M. Hashmi,Arooj Mubashara Siddiqui,M. Jabeen,Khurram Shehzad,Arif Zubair,Khurram Saleem Alimgeer +5 more
TL;DR: The analysis of the authentication protocols implemented in WiMAX has been presented along with the description of the threats posed to them and the proposed approach enhances the network security and strengthens it by resynchronization of the Subscriber Station with the Base Station.
