Antenna module for incorporation in wireless terminal equipment such as portable telephone

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.
