Inventor of the Month Winner

AHFR researcher Dr. Adam Narbudowicz was announced the winner of the Dublin Region Innovation Consortium (DRIC) [external]Inventor of the Month Competition for March.
Adam was involved in developing a low cost continuous radar system that measures the rotating speed of moving or stationary targets, enabling devices with hidden components to be serviced without being disassembled. The technology can be incorporated into radar systems or tracking devices.

Collaboration with RWTH Aachen

Prof Dirk Heberling, Dr Adam Narbudowicz and Prof Max Ammann at RTWH Aachen
DIT’s Antenna & High Frequency Research Centre (AHFR) has a long standing and a successful collaborative partnership with the Institut für Hochfrequenztechnik (IHF) at RWTH Aachen University which is ranked 145 in the QS World’s Top Universities.
This partnership was developed to a new level in January 2016 where Prof Max Ammann and Prof Dirk Heberling, Head of the IHF, oversaw joint discussions on closer collaboration across a range of project areas, which will benefit both institutions. The agreement secures access to the advanced measurement facilities at RWTH by AHFR. This includes a unique [external]compact antenna anechoic chamber, capable of standard far-field antenna measurement (2 - 75 GHz) but also near-field measurements from (800 MHz - 12 GHz) and radar cross-section measurements. The chamber (in the far-field configuration) has a quiet zone of 1.2 m diameter, with amplitude variation below 0.4 dB. Since such measurement facilities and corresponding expertise are not available at any Irish university, this strategic collaboration helps to position AHFR and DIT among leading researchers in antenna and microwave engineering research in Ireland.
The collaboration builds on an ongoing joint research project, funded by the [external]Irish Research Council with support from Marie Curie Actions. Dr. Adam Narbudowicz is currently involved in a two-year secondment at RWTH Aachen, where he is developing circularly polarized and pattern reconfigurable antennas for future telecommunication systems. The work has also seen PhD students from RWTH Aachen attend courses provided in DIT as part of the Telecommunications Graduate Initiative (TGI).

Best Student Paper Award at the Loughborough Antennas & Propagation Conference 2015

Kansheng Yang, a PhD student at the Antenna & High Frequency Research Centre (AHFR), School of Electrical & Electronic Engineering, was awarded an IET Best Student Paper Award at the Loughborough Antennas & Propagation Conference 2015, for his paper “A Back-to-Back Beam Switching Microstrip Patch Antenna", Kansheng Yang, Xiulong Baoand Max Ammann (Dublin Institute of Technology, Ireland). Kansheng is part of the CTVR/CONNECT Centre funded by Science Foundation Ireland and co-funded under the European Regional Development Fund under Grant Number 13/RC/2077.

Measurement Meets Simulation

CST and Rohde & Schwarz would like to invite you to a free joint workshop titled “Measurement Meets Simulation".

The workshop will include both presentations and hands on sessions where attendees will get to use CST STUDIO SUITE® 2014 software solutions and Rohde & Schwarz, test and measurement equipment.

This workshop aims to give engineers an insight into on how to achieve accurate simulations and show best practice guidelines to getting better measurements. Rohde & Schwarz will be demonstrating their new platforms ZNB and ZNC.

Participants will have ample opportunities to discuss technical questions with CST and Rohde & Schwarz staff.
Register online

Location: Dublin Institute of Technology, Kevin Street, Dublin 8, Ireland
Date: 9 Jul 2014
Time: 09:30 - 16:30
Registration and Coffee: 9:30 am

Provisional Agenda (10:00 am - 16:30 pm)

•Antenna Simulations and Numerical Modelling (CST)

AHFR Antenna launched with debut Decawave "Scensor"

DecaWave launches Scensor Chip with AHFR Antenna

Members of the Antenna and High Frequency Research Centre met with An Taoiseach Enda Kenny at Decawave’s launch of their Scensor Chip on the 7th November. The miniature integrated circuit exploits ultra wideband pulses to track assets with an accuracy of up to 7 cm. To help get their product to market, the AHFR team developed an antenna solution from the PhD research undertaken by Dr Matthias John and Dr Antoine Dumoulin.
DIT has a licence agreement with Decawave Limited on antenna design. The company have announced plans to double the workforce as they prepare to address market demand. Speaking at the event, Professor Max Ammann said, “It is exciting to see research backed by Science Foundation Ireland and Enterprise Ireland at the CTVR Telecommunications Research Centre in DIT become part of an Irish product and contribute to job creation. We wish Decawave’s CEO Ciaran Connell, CTO Michael McLaughlin and their team every success with the debut chip.”

DIT Inventor Competition Award 2012 for Adam Narbudowicz, Dr. Xiulong Bao and Prof. Max Ammann

DIT Inventor Competition Award 2012 for Adam Narbudowicz, Dr. Xiulong Bao and Prof. Max Ammann
Adam Narbudowicz, Dr. Xiulong Bao and Professor Max Ammann of the Antenna & High Frequency Research Centre took the postgraduate/staff prize in the DIT Inventor Competition 2012 for their Omni-Directional CP Antenna project. The award was presented by Minister for Research and Innovation Sean Sherlock.
The antenna can be used in WLAN routers and access points and means multiple antennas can be reduced to one. Its circular polarisation means devices can receive or transmit strong signals at any angle. This will improve connection quality and reduce distortion or streaming delays that occur when watching video on a poorly performing radio link. The antenna is also ideal for large spaces such as airport halls as its improved performance will reduce the number of access points needed to eliminate deadspots.
