摘要

A two-frequency antenna includes feeders 7a and 7b, inner radiation elements 2a and 2b connected to the feeders, outer radiation elements 3a and 3b, and inductors 4a and 4b that are formed in gaps 6a and 6b between the inner radiation elements and the outer radiation elements to connect the two radiation elements, which are printed on the first surface and on the second surface of the dielectric board 1, respectively.
