Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
91 words
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.
Claim 2
Dependent Claim
91 words
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.
Claim 3
Dependent Claim
51 words
The antenna according to claim 1 , wherein said radiation conductor unit includes two radiation conductors which are arranged in parallel to each other with a slit therebetween, and wherein one or more of said projections are inserted into said slit and are engaged with each of said two radiation conductors.
Claim 4
Dependent Claim
25 words
The antenna according to claim 1 , wherein one or more of said projections abut against the peripheral edges of said plurality of radiation conductors.
Claim 5
Dependent Claim
45 words
The antenna according to claim 1 , wherein one or more of said projections are provided with a thinned portion for restraining the displacement of said plurality of radiation conductors in the thickness direction by fitting said plurality of radiation conductors on said thinned portions.
Claim 6
Dependent Claim
36 words
The antenna according to claim 1 , wherein said insulating casing is constructed by fixing a pair of cases to each other with screws, and wherein one or more of said projections serve as screw-receiving portions.
