COST Action IC0603 4th Management Committee Meeting & Workshop

The (external)DITs Antenna & High Frequency Research Group (AHFR) and the (external)Centre for Telecommunications Value-Chain Research (CTVR) are co-organising this years COST Action IC0603 'ASSIST' 4th Management Committee Meeting & Workshop on "Antenna Systems & Sensors for Information Society Technologies".

The workshop will cover the topics of the different Working Groups of COST IC0603, along with guest presentations on related matters. The meeting and workshop will be held on 1-3 October 2008 at the CTVR headquarters in Trinity College, University of Dublin.

A website has been set up at http://cost.ahfr.dit.ie to help organise the meeting and workshop.

DIT PhD researcher accepts invitation to study 'Cancer Therapy Hyperthermia Applicators' in Singapore

Zhi Ning Chen and Sergio Curto at I2R
Mr Sergio Curto, a PhD student from the Antenna & High Frequency Research Group at the School of Electronic and Communications Engineering has been invited to visit the laboratories at the Institute for Infocomm Research (I2R), Singapore to complete specialist measurements on a novel cancer therapy applicator that he is researching. The deployment of temperature raising radiowaves in tumour regions of the body, as an adjunctive therapy, requires an antenna that will operate efficiently when in close proximity to human tissue. The I2R have a shared interest in these antenna applicators and have extensive experience in the measurement of SAR, the parameter that defines the rate of radiowave energy absorbed into the human body. Their measurement equipment, known as a Dosimetric Assessment System, employs fluids with the equivalent electrical properties of human tissue to estimate the exposed energy pattern due to a nearby radiator.

The two institutes are following on successful collaboration between Dr Max Ammann, DIT’s School of Electronic & Communications Engineering and Professor Zhi Ning Chen, the [external]Institute for Infocomm Research I2R, Singapore. During a three month period it is hoped that an exchange of ideas will improve the understanding of how to optimise such devices. It is a complementary approach to research that has resulted in lowered emission exposure to users of mobile telephones.

The Dublin Institute of Technology’s Antenna & High Frequency Research Group has particular expertise in antenna designs suited to handheld communications terminals. The small dimensions of these antennas and their susceptance to performance changes when near people has led to size reductions and efficiency enhancements in cancer therapy applicators. The modelling work will benefit from measurement experiments and validation in I2R This work is funded by the Irish Research Council for Science, Engineering and Technology under the Embark Initiative, which supports PhD studies ([external]http://www.ircset.ie).

PhD Student Wins Best Poster Award at the CTVR 2007 Annual Plenary Meeting

Best PosterMr Matthias John, who is researching novel Spline shaped antennas, was awarded a CTVR gift certificate in recognition of The Best Poster Award at the 2007 (external)CTVR Annual Plenary Meeting. In the presentation, Prof Donal O’Mahony of Trinity College Dublin and chairman of the CTVR, acknowledged the very high standard of engineering research exhibited in the 45 posters at the event. Matthias is in the third year of his PhD research on "Evolutionary Design Methodologies for Small Ultra Wideband Antennas."

DIT Antenna Research Expands

With continued growth in requirements for consumer electronics, the Antennas & High Frequency Research Group, within the (external)DIT School of Electronic & Communications Engineering, has capitalised on recent successes to expand their investigative portfolio.

While advancing design principles for antennas in portable communications and medical applications, the group has recruited new personnel with funding for antenna technologies in multimedia consumer electronics and renewable energy systems.

Their recent technology transfer initiative, supported by [external]Enterprise Ireland's Commercialisation Fund for proof-of-concept prototyping, is focused on high performance, low cost Ultra Wideband [external](UWB) antennas. These enabling components are fundamental to an emerging standard for multimedia wireless communication between items in modern life, such as digital cameras, high definition screens, DVD players, mobile phones and computer printers. UWB will both eliminate the need for interconnecting cables and reduce data transfer times over short distances within living spaces at home or in the office.

Strengthened to three research associates and nine research students, the group has a range of simulation and measurement tools to facilitate solutions in wireless communications design. The group's work is aligned to the Centre for Telecommunications Value-Chain Research [external](CTVR) and benefits from collaboration with other academic groups and industrial partners.

PhD Student Wins Best Poster at International Conference

Mr Giuseppe Ruvio received a best paper/poster award by popular vote and committee approval at the Loughborough Antennas and Propagation Conference in April 2006. The conference had more than 100 papers from more than 25 countries across the world. His work focuses on novel miniature high performance antennas for emerging wireless systems, such as Ultra Wideband systems. Giuseppe, received his master's degree from the University of Siena, Italy, before coming to work in Ireland on a European Space Agency funded antenna project in industry. He has since joined the Centre for Telecommunications Value-chain-driven Research ([external]www.ctvr.ie) antenna group, based in the School of Electronic & Communications Engineering, Kevin St. He is currently reading for PhD in the field of metamaterial enhanced antenna technology.

Dr Xiulong Bao Receives CTVR Achievement Award

Dr Xiulong Bao, a researcher in the Centre for Telecommunications Value-chain-driven Research (CTVR, [external]www.ctvr.ie) antenna group, located in the School of Electronic & Communications Engineering, Kevin St received an achievement award based on research output at the CTVR plenary meeting in Kilkenny in March. The antenna group is part of the larger RF strand, based in NUI, Maynooth, whose aim is to realize the next generation of fully reconfigurable radio transceivers and associated intelligent antenna systems. Bell Labs Research Ireland are partners in the project.

Dr Bao received his M.Sc and Ph.D degrees from the Southeast University, Nanjing, China in 1996 and 2003 respectively. His major is electromagnetic fields & microwave technology. His research fields comprise GPS/handset antennas, RFID antennas, and various antennas based on metamaterial structures. He has considerable skills in electromagnetic scattering and electromagnetic numerical computation.

He held a post-doctoral post in the Shanghai Jiao Tong University for the next two years, before coming to Ireland. His work, in Dublin involves the miniaturisation of antennas for emerging telecommunications systems and improvement of antenna performance using novel metamaterials.

CTVR Test Standard Hopping Wireless System

A wireless system capable of hopping between incompatible wireless standards that could revolutionise the telecommunications industry is being tested in Ireland. The "software-defined radio" device, developed by a team at the Centre for Telecommunications Value-Chain Research (CTVR) in Dublin, can mimic many different wireless tools by using reconfigurable software to carry out tasks normally performed by static hardware. The system employs novel radio frequency (RF) and antenna elements, developed by the CTVR antenna group, School of Electronic and Communications Engineering, Kevin St. This group is part of the larger RF strand, aimed at realizing the next generation of fully reconfigurable radio transceivers and associated intelligent antenna systems.
