Metallic EBG Sectoral Antennas with different Polarizations

摘要

This work aims to study and design antennas for base stations with metallic electromagnetic band gap (EBG) materials. The objective was to make and study new concepts of EBG metallic antennas able to work according to a wide (or broad) radiation pattern form, I.e. presenting at least 60° angular beamwidth. The use of metallic structures offers a new approach to industrial partners in order to reduce costs and to facilitate design techniques. The high impedance presented by the metallic structure allows us to use only one layer of rods and to make the antenna more compact than the one with a dielectric structure.%Svrha je rada prou?avanje I prora?un antena za bazne stanice koje sadr?e metalne materijale s elektromagnetskim zapornim pojasevima (EBG). Cilj je bio ostvariti I prou?iti nove koncepcije metalnih EBG-antena koje bi radile sa ?irokim oblikom dijagrama zra?enja, tj. S kutnom ?irinom snopa od barem 60 stupnjeva. Uporaba metalnih struktura nov je pristup koji nudi industrijskim partnerima mogu?nost smanjenja tro?kova I ujedno im olak?ava tehnologiju izrade. Visoka impedan-cija metalne strukture omogu?uje uporabu samo jednog sloja ?ica, kao I izradu kompaktnije antene u odnosu na onu s dielektri?nom strukturom.
