Colinear antenna of the alternating coaxial type

摘要

The invention relates to an antenna of colinear type. It comprises a radiating portion comprising: three substantially rectilinear conductive wire elements that are mutually parallel, comprising a central conductor and two lateral conductors; and 2 N radiating zones constituted by alternating first radiating zones and second radiating zones: each first radiating zone further comprising a cylindrical conductive element whose axis coincides with said central wire element and which is electrically connected to both of said lateral wire elements; and each second radiating zone further comprises two cylindrical conductive elements whose axes coincide substantially respectively with the lateral wire elements, said cylindrical elements being electrically connected to said central wire element.
