Meeting the challenges of RF with mmWave for 5G

Millimeter wave (mmWave) frequencies in combination with small Radio Frequency (RF) coverage look to be key technologies for 5G networks. However, mmWave spectrum comes with high path losses and the solution of small RF coverage to reduce signal congestion suffers from distortions of the transmitted signals. This webinar will look at how measurements of RF front ends designed for mmWave can help address whether commercial-off-the-shelf chip-based RF front end technology is ready to be used for 5G networks.


Rafael F. S. Caldeirinha (Fellow Member IET and Senior Member IEEE) received the BEng (Hons) degree in Electronic and Communication Engineering from the University of Glamorgan, UK, in 1997. In 2001, he was awarded a Ph.D in Radiowave Propagation by the same University for his research work in vegetation studies at frequencies from 1 to 62.4 GHz. He is currently Head of the Antennas & Propagation (A&P-Lr) research group at Instituto de Telecomunicações, Leiria, Portugal, and Coordinator Professor in Mobile Communications at the School of Technology and Management (ESTG) of the Polytechnic Institute of Leiria (IPLeiria), Portugal.
His research interests include studies of radiowave propagation through vegetation media, radio channel sounding and modeling and frequency selective surfaces, for applications at microwave and millimetre wave frequencies.

Prof. Caldeirinha has authored or co-authored more than 120 papers in conferences and international journals and 4 contributions to ITU-R Study Group, which formed the basis of the ITU-R P.833-5 (2005) recommendation. He is Associate Editor of the IEEE Transactions on Antennas and Propagation journal; Associate Editor of the IET on Microwaves, Antennas and Propagation journal; Member of the editorial board of the International Journal of Communication Systems, IJCS (New York, Wiley); Program chair of WINSYS International Conference between 2006 and 2012; Appointed Officer for Awards and Recognitions of the IEEE Portugal section in 2014; Chair of the IEEE Portugal Joint Chapter on Antennas & Propagation - Electron Devices - Microwave Theory & Techniques since 2016; Regional Delegate of European Association for Antennas and Propagation (EurAAP) for Andorra, Portugal and Spain since March, 2017; and a Senior Member of IEEE and Fellow Member of IET.
