Conformación del diagrama de radiación de un monopolo en L

Abstract

The typical radiation pattern of an L-monopole antenna can be easily modified by changing the geometrical characteristics of the structure. To shape a specific radiation pattern through a basic structure becomes an interesting freedom degree in order to better adapt the behaviour of the antenna to the design specifications. Thus, to solve the question,an accurate analysis following the radiated field basic equations has been carried out. The theoretical study is validated through a simulation and experimental process. The results depict three main regions, delimited by geometrical boundaries, where the Lshaped wire antenna present three specific radiation pattern types, a monopole-type, a half isotropic type or even, a patchtype radiation pattern. Consequently, the method described herein demonstrates that simple modifications applied to the geometry of a basic structure, allow obtaining radiation properties associated to more complex structures.Peer ReviewedPostprint (published version
