A dielectric member comprising a laminated balun and a matching circuit, wherein the matching circuit is integrally mounted within the laminated balun. The matching circuit comprises a patterned conductive film formed on a surface of an existing dielectric substrate in the balun such that the balun is not increased in size.

Laminated balun with an integrally mounted matching circuit

A dielectric antenna module () includes an antenna element unit () having an antenna element () consisting of a radiation electrode () and a signal line () formed on a dielectric substrate (), and a module substrate unit () having a signal processing circuit formed on a module substrate (). The substrate () are arranged and connected to each other so that their bottom surfaces form a single plane. The antenna element unit () and the module substrate unit () are connected to each other by fitting a projection () to a recess () formed on and in the opposing faces of the substrates (). On the projection () and in the recess (), signal lines () are formed, respectively, and on the opposing faces of the substrates (), ground electrodes () are formed. When the projection and recesses are engaged, the signal lines () are connected to each other and the ground electrodes () are connected to each other. A base film () where a ground electrode is formed is attached to the bottom surface of the substrates ().
