Abstract
An antenna includes a radiation conductor unit constructed with a plurality of radiation conductors having different lengths which extend in parallel to each other from an electricity-supplying conductor and a grounded conductor unit which opposes said plurality of radiation conductor in an approximately parallel manner with a predetermined distance therebetween. The radiation conductor unit and the grounded conductor unit are contained in an insulating casing constructed by a pair of cases which is fixed to each other. The casing is provided with a plurality of projections for positioning the radiation conductor unit and the grounded conductor unit.
Claims5
An antenna comprising:
- a radiation conductor unit including an electricity-supplying conductor and a plurality of radiation conductors having different lengths which extend in parallel to each other from said electricity-supplying conductor;
- a grounded conductor unit which opposes said plurality of radiation conductors in an approximately parallel manner with a predetermined distance therebetween;
- an insulating casing which contains said radiation conductor unit and said grounded conductor unit;
- and
- a plurality of projections in an inwardly facing surface of said insulating casing for positioning said radiation conductor unit and said grounded conductor unit.
