Abstract

An improved broadband omnidirectional antenna is distinguished by the following features: the omnidirectional antenna is in the form of a dual-polarized antenna, the dual-polarized antenna comprises a horizontally polarized radiating element (3) in addition to the vertically polarized radiating element (1; 1a, 1b) which is in the form of a monopole, the horizontally polarized radiating element (3) comprises slots (43, 43′) which are provided offset in the circumferential direction in the casing (11a) of the vertically polarized radiating element (1; 1a, 1b) which is in the form of a monopole, a feed device (111) for the horizontally polarized radiating element (3) being provided in the interior (11d) of the vertically polarized radiating element (1; 1a, 1b) which is in the form of a monopole, and the feed device (111) comprises separate feed devices (111a) for a plurality of slots (43, 43′), the respectively associated slots (43, 43′) being separately excited by means of said feed devices.
