Planar antenna.

摘要

A planar antenna comprises a dielectric layer (2) comprising a homopolymer of 3-methylbutene-1 or a copolymer of 3-methylbutene-1 and an alpha-olefin of from 2 to 12 carbon atoms and/or a polyene, a conductor (1) laminated onto the whole of the back surface of the said dielectric layer (2) and a circularly polarized radiation microstrip element (3) formed from a metal foil and provided on the other surface of the said dielectric layer (2).
