Abstract (en)

[origin: US6861988B2] 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 for a patch antenna element arrangement (7), which is constructed on it, for the higher frequency band,a slot arrangement which has an H-shaped slot structure (11, 13) is formed in at least one feed patch (5a, 7a), andthe at least two slot structures (11, 13) in the respective feed patch (5a, 7a) are fed via a respectively associated feed cable arrangement (15a, 15b).
