A compact hairpin filter with stepped hairpin defected ground structure
(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 ...
ISM band 1:16 wilkinson power divider
(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
(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 ...
Statistical modeling of propagation channels for Terahertz band
(Institute of Electrical and Electronics Engineers Inc., 2017)
Digital revolution and recent advances in telecommunications technology enable to design communication systems which operate within the regions close to the theoretical capacity limits. Ever-increasing demand for wireless ...
IEEE 802.11af ve 802.22 sistemlerinin uyumlu çalışmaları için meşgul ton tabanlı güç kontrolü
(Institute of Electrical and Electronics Engineers Inc., 2017)
Bu bildiride, IEEE 802.22 ve IEEE 802.11af kablosuz sistemlerinin TV beyaz boşluğunda uyumlu çalışabilmeleri için meşgul ton tabanlı yeni bir güç kontrol algoritması önerilmiştir. Daha önceki meşgul ton tabanlı çalışmalardan ...
Adaptive bit-loading in relay-aided cognitive radio network
(Institute of Electrical and Electronics Engineers Inc., 2017)
In this work, we consider a joint power allocation and bit loading problem in an orthogonal frequency division multiplexing (OFDM) based cognitive radio (CR) network. The objective is to maximize the end-to-end rate in a ...
Roger F. Harrington, 1989 IEEE AP-S distinguished achievement awardee
(Institute of Electrical and Electronics Engineers, 2017)
Roger F. Harrington is widely recognized as one of the key figures in electromagnetics of the latter half of the twentieth century. He is most well-known for his development of the Method of Moments (MoM) and for his ...
Numerical characterization of in vivo wireless communication channels
(Institute of Electrical and Electronics Engineers Inc., 2014)
In this paper, we numerically investigated the in vivo wireless communication channel for human male torso at 915 MHz. Results show that in vivo channel is different than the classical communication channel and location ...
Controlled inter-carrier interference for physical layer security in OFDM systems
(Institute of Electrical and Electronics Engineers Inc., 2016)
Performance of OFDM is known to be very sensitive to frequency synchronization errors. By exploiting this feature, a novel technique is proposed to provide secure communication against eavesdropping. The technique is based ...
Mobility performance of macrocell-assisted small cells in Manhattan model
(Institute of Electrical and Electronics Engineers Inc., 2014)
Macrocell-assisted small cell concepts, such as "Phantom cell concept" and "soft cell concept", have been proposed previously for interference management, flexible cell planning, and energy saving in dense small cell ...
