FIELD: physics, radio. ^ SUBSTANCE: invention is related to the field of antenna engineering and may be used in stationary, portable and mobile radio equipment. Wideband antenna comprises upper conical radiator (2), with cone top of which central core of coaxial cable (1) is connected, external conductor (1.2) of which is connected to counterbalance part (3). At that wideband matching device (WMD) (5) and lower conical radiator (4) are introduced. Ratio of lengths of cone generatrixes of conical radiators (2) and (4) makes 2:1, and angles of both conical radiators relative to vertical axis of cones make 45 degrees, at that WMD (5) is connected into break of coaxial cable (1). Lower conical radiator (2) is connected from opposite ends of its cone generatrix to external conductor (1.2) of coaxial cable (1) and to counterbalance part (3) accordingly. ^ EFFECT: expansion of working frequencies range with preservation of radiated power along ground surface. ^ 2 dwg |
