Sidelobe Reduction of Antenna Arrays using Metamaterials

Theme:

Antenna design / Communication

Application:

Communications and Radar

Contact Person:

Goal:

Design and optimise passive metasurface unit cells that exhibit frequency-dependent reflection and transmission characteristics tuned for sidelobe suppression.
Optimise the planar metasurfaces with antenna arrays using simulation (Ansys HFSS, CST) and analyse the radiation patterns (mainlobe gain, sidelobe levels, beamwidth, cross-polarization) with and without meta surface.

Requirements:

Background in Electrical Engineering
(Preferably) familiarity with CST or Ansys HFSS simulation tools
