An antenna module suitable for a reduction in size and weight of equipment and improved in manufacturability. The antenna module includes a ground element formed from a planar conductor, an antenna element formed from a planar conductor and arranged in parallel to the ground element, and a loop element formed from a tubular conductor and arranged between the ground element and the antenna element in predetermined positional relationship with both elements so as to be connected with the antenna element. The loop element has a first hollow portion passing therethrough in a given direction. The antenna module further includes an element support formed from an insulator and arranged so as to fill a space between the ground element and the antenna element and substantially fully cover an outer surface of the loop element. The element support is formed with a second hollow portion passing therethrough in the same direction as that of the first hollow portion of the loop element.

Antenna module for incorporation in wireless terminal equipment such as

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.
