An antenna module capable of finely adjusting the resonant frequency and having an antenna element exclusively used for radio transmission and reception to provide a broad frequency band characteristic. This antenna module is composed of a dielectric substrate molded in a predetermined shape, a grounding conductor in the form of sheet provided on one surface of the dielectric substrate, and antenna element conductor in the form of sheet provided on the opposite surface to the above one surface and having end portion being almost V-shaped end folded, and an adjusting member inserted into the almost V-shaped folded end portion.

Antenna module for a portable radio equipment with a grounding conductor

A manufacturing method for plural antenna modules which is suitable for mass production. Each antenna module includes a ground element, an antenna element, a loop element, and an element support. The manufacturing method for the antenna modules includes a first step of setting in a mold a first conductive base material including a plurality of the ground elements integrally connected together, a second conductive base material including a plurality of the antenna elements integrally connected together, and a third conductive base material including a plurality of the loop elements integrally connected together; a second step of filling a cavity defined in the mold with a curing fluid and then curing the curing fluid to thereby form an element support base material including a plurality of the element supports integrally connected together; and a third step of cutting the element support base material together with the first, second and third conductive base materials to thereby obtain a plurality of the antenna modules.
