Presentation / Conference Contribution
Mehdawi, M., Riley, N. G., Fanan, A., & Ammar, M. (2016, November). Influence of antenna selection on spectrum occupancy measurements in the context of cognitive radio. Presented at 24th Telecommunications Forum, TELFOR 2016

© 2016 IEEE. Cognitive radio (CR) has been proposed as a solution to the spectrum scarcity problem, which is aggravated by emergence of bandwidth-hungry and feature-rich wireless applications. Selection of appropriate antennas for cognitive radio app... Read More about Influence of antenna selection on spectrum occupancy measurements in the context of cognitive radio.

Quality measurements of an UWB reduced-size CPW-fed aperture antenna (2016)
Book Chapter
Zolfaghari, M., Riley, N. G., Mehdawi, M., Fanan, A., Ammar, M., & Meng, F. (2016). Quality measurements of an UWB reduced-size CPW-fed aperture antenna. . Institute of Electrical and Electronics Engineers. https://doi.org/10.1109/TELFOR.2015.7377526

The paper presents a characterization of a compact co-planar waveguide (CPW)-fed slot loaded low return loss planar printed antenna designed for wireless communication and ultra-wideband (UWB) applications. Following a review of the antenna design, w... Read More about Quality measurements of an UWB reduced-size CPW-fed aperture antenna.

Spectrum occupancy measurements and lessons learned in the context of cognitive radio (2016)
Presentation / Conference Contribution
Mehdawi, M., Riley, N. G., Ammar, M., Fanan, A., & Zolfaghari, M. (2015, November). Spectrum occupancy measurements and lessons learned in the context of cognitive radio. Presented at 2015 23rd Telecommunications Forum, TELFOR 2015

Various measurement campaigns have shown that numerous spectrum bands are vacant even though licenses have been issued by the regulatory agencies. Dynamic spectrum access (DSA) based on Cognitive Radio (CR) has been regarded as a prospective solution...

A slot-loaded reduced-size CPW-fed aperture antenna for UWB applications (2013)
Presentation / Conference Contribution
Zolfaghari, M., Riley, N. G., Mahdawi, M., & Shen, J. (2013, November). A slot-loaded reduced-size CPW-fed aperture antenna for UWB applications. Presented at 2013 Loughborough Antennas and Propagation Conference, LAPC 2013

The paper presents a co-planar wave guide (CPW)-fed slot loaded low return loss planar printed antenna with a small size designed for wireless communication and UWB applications. First, a conventional UWB antenna is modeled to provide a reference poi... Read More about A slot-loaded reduced-size CPW-fed aperture antenna for UWB applications.

Comparing historical and current spectrum occupancy measurements in the context of cognitive radio (2012)
Presentation / Conference Contribution
Mehdawi, M., Riley, N., Ammar, M., & Zolfaghari, M. (2012, November). Comparing historical and current spectrum occupancy measurements in the context of cognitive radio. Presented at 2012 20th Telecommunications Forum (TELFOR)

Cognitive radio (CR) technology promises to be one possible solution to solve the problem of lack of frequency spectrum, by allowing access of unlicensed users in licensed bands, based on an opportunistic approach and without interfering with the lic...
