Beam forming dielectric cylindrical EBG antenna

Design of a Beam Forming Dielectric Cylindrical Ebg Antenna

“…In [19] the authors presented the simulation results of a novel dielectric CEBG antenna realized with dielectric rods arranged in a simple multilayer cylindrical geometry similar to the one proposed in [16,17], showing that the aforementioned geometry can also be used to create dielectric CEBG structures. Beam forming and high directivity on the azimuthal plane were achieved by breaking the CEBG structure cylindrical periodicity with an angular defect window: radiation is allowed in the defect direction and forbidden in the opposite directions by the existing bandgap.…”

“…In this paper we present the simulations and measurements results of a parametrical study carried out on the CEBG antenna structure presented in [19]. The aim of this study is to analyse the relationships between geometrical parameters and antenna performances.…”

“…A similar approach to [17,19] has been used: an in-house developed Finite-Difference-Time-Domain (FDTD) simulator has been used to characterize 2D CEBG structures in terms of transmission coefficient and bandgap frequencies; these information have been used to design a 3D CEBG structure; the 3D CEBG structure has been parametrically studied with FDTD simulations and measurements carried out on prototypes built using cylindrical ceramic rods with dielectric constant equals to 76.5.…”
