Abstract

Abstract An antenna includes a casing which is constructed of a first case and a second case. In the first case, a radiation conductor unit including an electricity-supplying conductor and a plurality of radiation conductors having different lengths and a grounded conductor unit including a ground conductor are contained. The radiation conductors extend in parallel to each other from the electricity-supplying conductor. A first receiving portion provided in the electricity-supplying conductor and a holding portion and a second receiving portion provided in the grounded conductor unit are arranged in a linear manner. A coaxial cable is introduced from the upper side, and an inner conductor and an outer conductor of the coaxial cable are connected to the first and the second receiving portions, respectively. In addition, the holding portion holds an insulator of the coaxial cable. The opening at the upper side of the first case is then covered by the second case.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 144 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; and an insulating casing which contains said radiation conductor unit and said grounded conductor unit, and which is constructed of a main case and a cover which are able to sandwich a coaxial cable for supplying electricity, wherein said radiation conductor unit and said grounded conductor unit are fixed to said main case, and wherein a connecting part of an inner conductor of said coaxial cable and said electricity-supplying conductor and a connecting part of an outer conductor of said coaxial cable and said grounded conductor unit are covered with said cover.
Claim 2
Dependent Claim 144 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; and an insulating casing which contains said radiation conductor unit and said grounded conductor unit, and which is constructed of a main case and a cover which are able to sandwich a coaxial cable for supplying electricity, wherein said radiation conductor unit and said grounded conductor unit are fixed to said main case, and wherein a connecting part of an inner conductor of said coaxial cable and said electricity-supplying conductor and a connecting part of an outer conductor of said coaxial cable and said grounded conductor unit are covered with said cover.
Claim 3
Dependent Claim 72 words
An antenna according to claim 1 , wherein said electricity-supplying conductor is provided with a first receiving portion to which the inner conductor of said coaxial cable is connected, wherein said grounded conductor unit is provided with a second receiving portion to which the outer conductor of said coaxial cable is connected, and wherein said first receiving portion and said second receiving portion are positioned in the same direction of said antenna.
Claim 4
Dependent Claim 37 words
An antenna according to claim 2 , wherein a vertical distance between said first receiving portion and said grounded conductor unit is larger than a vertical distance between said second receiving portion and said grounded conductor unit.
Claim 5
Dependent Claim 41 words
An antenna according to claim 1 , wherein said coaxial cable is provided with a thickened portion at an exterior of said coaxial cable, and wherein said main case and said cover are provided with concavities for receiving said thickened portion.
Claim 6
Dependent Claim 53 words
An antenna according to claim 1 , wherein at least one of said radiation conductor unit and said grounded conductor unit is provided with a holding portion for holding said coaxial cable, and wherein an end portion of said grounded conductor unit abuts against an inwardly facing side surface of said main case.
