Title: Wideband antenna mountable in vehicle cabin

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.
