Antenna module for incorporation in wireless terminal equipment such as portable telephone
First Claim
1. An antenna module having two opposing sides and comprising:
- a ground element formed of a planar conductor;
an antenna element formed of a planar conductor, said antenna element being arranged substantially parallel to said ground element;
a loop element formed of a tubular conductor, said loop element being arranged between said ground element and antenna element in predetermined positional relationship with both said ground and antenna elements and being electrically connected with said antenna element, said loop element having a first hollow portion extending therethrough in a direction perpendicular to the opposing sides of said antenna module; and
an element support formed of an insulator, said element support being arranged so as to fill a space between said ground element and said antenna element and substantially fully cover an outer surface of said loop element, said element support having a second hollow portion extending therethrough in the same direction as that of said first hollow portion of said loop element and in parallel therewith.

Abstract
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.
