Joana Santos Tavares
Joana Tavares completed the Master Course in Electrical and Computer Engineering in 2012 and the Doctoral Programme in Telecommunications (MAP-tele) in 2021, both at the Faculty of Engineering of the University of Porto (FEUP). She has been a research fellow since 2014 in the Optical and Electronic Technologies (OET) group from the Centre of Telecommunications and Multimedia at the Institute for Systems and Computer Engineering, Technology and Science (INESC TEC). Currently, she is an Invited Assistant Professor at the Department of Electrical and Computer Engineering of FEUP. Her main research interests include optical fiber communication systems and smart antenna arrays.
Projects
iBROW
iBROW aims at developing a novel, low-cost, energy-efficient and compact ultra-broadband short-range wireless communication transceiver, capable of addressing future network usage requirements. This will be pursued using Resonant Tunnelling Diode (RTD) devices which are the fastest pure solid-state electronic devices operating at room temperature, with reported working frequencies exceeding 1 THz. By developing a unified technology that can be integrated into both ends of the wireless link, namely consumer portable devices and fibre-optic supported base-stations, the project aims at increasing the RTD output power, optical detection efficiency and energy efficiency at target frequencies, enabling high-speed short-range wireless communications.
STRx
The STRx project proposes to research and develop an electronically guided signal transmission and reception system to function with the next generation of non-stationary orbit satellites. It will initially target the business and terrestrial mobility sectors and subsequently the domestic sector, where implementation and operation of the fixed infrastructure is not feasible, once the cost structure has been optimized. The consortium promoter, constituted by Sinuta, Instituto de Telecomunicações, and INESC TEC, encompass/have an important skill set for the technical-scientific challenges of the project, in the fields of electronic, signal processing, computer programming, and radio frequency elecommunications. The innovative approach of the project is clearly visible in 4 points: Integration of emerging technologies (MMIC) to this application; dynamic adaptation of ?beamforming?; radiation pattern synthesis method; beam range scanning of elemental antennas. Objectively, the results of STRx project will enable a low-cost and high data transfer system of electronically guided antennas, to operate with non-stationary orbit satellites, filling the gap in t.
