Focusing Antenna Systems

Focus Area: Focusing Antenna Systems

Background
At millimetre (mm) and sub-mm waves, moderate or high-gain radiating structures are key devices to establish point-to-point and point-to-multipoint radio links for far-field and near-field applications, such as: high data-rate communication indoor & outdoor systems (smart home, gigabit offices), communication with satellites and moving platforms, intelligent transport systems, passive and active imaging / sensing, security and surveillance systems in public areas, etc.

In this area, quasi-optical technologies, and in particular dielectric and metallic focusing systems, are very attractive due to their promising figure of merit in terms of performance and cost. The main antenna technologies covered by this Working Group include any integrated dielectric focusing / collimating system built from arbitrary focusing devices (dielectric or metal-dielectric lenses of various shapes and sizes, and made of different constitutive materials) combined with a set of arbitrary primary feeds or detectors (e.g. 2-D or 3-D passive or active devices) that can be integrated at the “system” base and arranged into arrays to design a reconfigurable, beam forming or beam steering antenna systems.

Objectives
The major goal of this WG is to gather and share expertise and know-how on dielectric focusing systems (and feeds) spread all over Europe in order to strengthen and consolidate education and research in this field. To reach this goal the following objectives are formulated:
  • Maintain and strengthen the networking in the field of focusing / collimating antenna systems in Europe
  • Contribution to the development of advanced electromagnetic modelling techniques using complementary formulations for the analysis, synthesis and optimizations of integrated dielectric focusing systems
  • Contribution to the implementation of powerful CAD tools
  • Consolidation of research efforts aimed at innovations in the mm and sub-mm technologies with a particular emphasis on integrated dielectric focusing systems
  • Contribution to the benchmarking measurement facilities at mm and sub-mm waves
  • Promotion of researchers’ mobility and exchange of researchers and students for missions dedicated to a specific aim
  • Follow-up emerging applications, technologies and materials
  • Support to the courses of the European School on Antennas in the field of this WG
Organization
This Working Group originates from various institutions previously involved in ACE and ACE-2.
The Management Committee will meet at least once a year (for instance in parallel to other scientific events like EuCAP conference, EuMW, COST VISTA meetings, etc.), and use other means such as e-mail or teleconferences to keep a continuous communication.

To promote this rapidly developing research domain, a research and network project entitled "New frontiers in mm / sub-mm waves integrated dielectric focusing systems" (acronym NEWFOCUS) has been recently proposed to and supported by the European Science Foundation (ESF) under the Research Networking Program (RNP) scheme.

RNP NEWFOCUS gathers 12 research teams from Austria, Belgium, Croatia, Finland, France, Germany, Italy, Portugal, Switzerland, The Netherlands, UK, and Ukraine.
These teams have strong background and expertise in the relevant fields and currently focus their research and networking activities onto generic integrated dielectric focusing systems and their associated feeds / sensors.
