Coaxial collinear element array antenna

An antenna comprising:

• a plurality of coaxial transmission lines each having an inner conductor having an outer diameter and an outer conductor having an inner diameter, said inner conductor of each coaxial transmission line being soldered to said outer conductor of a next adjacent coaxial transmission line;
• coupler means positioned between each coaxial transmission line and said next adjacent coaxial transmission line for supporting said inner and outer conductors of said each coaxial transmission line and said next adjacent transmission line in a manner that maintains concentricity of inner and outer conductors of adjacent transmission lines;
• said coupler means including a dielectric coupler constructed of dielectric material comprising a central disk having a predetermined diameter and offset outer conductor supports positioned on opposite sides of said central disk, said outer conductor supports having outer diameters substantially equal to said inner diameter of each outer conductor and concentric with an inner conductor through-passage in said central disk having a diameter substantially equal to said outer diameter of each inner conductor, said offset of said outer conductor supports is established so that said inner conductor of a coaxial transmission line passed through said inner conductor through-passage is in substantial contact with said outer conductor of said next adjacent coaxial transmission line.
