Abstract: An improved dipole-type radiator arrangement is characterized, inter alia, by the following features: a second two-line system (21.1b; 21.2b) is provided for the at least one polarization plane (P1, P2), the second two-line feed system (21.1b; 21.2b) likewise comprises a feed by means of a signal line (27.1b; 27.2b) and by means of a ground line (25.1b; 25.2b), the second two-line feed system (21.1b; 21.2b) is provided opposite the first two-line feed system (21.1a; 21.2a) with regard to the two radiator halves (7.1a, 7.1b; 7.2a, 7.2b) such that the associated second signal line (27.1b; 27.2b) is galvanically or capacitively coupled to the first radiator half (11.1a; 11.2a), and the associated ground line (25.1b, 25.2b) is galvanically or capacitively coupled to the associated second radiator half or mount half (7.1b, 11.1b; 7.2b, 11.2b).

Abstract: An improved patch antenna for operation in at least two frequency bands is distinguished by the following features: having a reflector (1), at least two patch antenna element arrangements (5, 7) are provided, constructed on the reflector (1) and/or arranged in front of the reflector (1), namely a patch antenna element arrangement (5) for a lower frequency band and a patch antenna element arrangement (7) for a higher frequency band, the patch antenna element arrangements (5, 7) for the lower frequency band and for the higher frequency band each have at least one active feed patch (5a, 7a) with an associated slot structure (11, 13) and a passive cover patch (5b, 7b), which is arranged above it and is capacitively coupled, the patch antenna element arrangements (5, 7) for the lower frequency band and for the higher frequency band located on a base plate, the top cover patch (5b) of the lower patch antenna element arrangement (5) for the lower frequency band in this case at the same time forms the base plate f
