Metamaterial-based, wideband, planar antennas at 140 GHz
Metamaterials are some of the most well-known artificial materials and exhibit unusual electromagnetic properties. Metamaterials’ remarkable properties play a crucial role in modern antenna design. Antennas can be used with artificial materials to improve several of their properties, including their bandwidth and radiation patterns. Various types of metamaterials have been proposed in the literature - classification of metamaterials depend on their permittivity and permeability parameters. Some examples of metamaterials used with planar antennas include Split Ring Resonators (SRRs), Zero Order Resonators (ZORs), Right/Left Handed Materials (RHM/LMH) and Electromagnetic Bandgap (EBG) materials.
In this thesis, the aim is to investigate different metamaterial unit cell options for wideband antennas at 140 GHz. Design and manufacture a wideband metamaterial-based antenna or antenna array at 140 GHz.
