Patch antenna for operating in at least two frequency ranges

本发明涉及工作于至少两个频率范围内的优化补件天线，其特征在于：a)具有一个反射器(1)，b)在反射器(1)之上和/或在反射器(1)之前设置至少两个补件辐射装置(5，7)，即一个用于较低频率范围的补件辐射装置(5)和一个用于较高频率范围的补件辐射装置(7)，c)用于较低频率范围和用于较高频率范围的补件辐射装置(5，7)分别包括至少一个具有相应缝隙结构(11，13)的有源馈电补件(5a，7a)和一个安装在馈电补件上方的、电容耦合的无源遮盖补件(5b，7b)，d)用于较低频率范围及用于较高频率范围的补件辐射装置(5，7)设置在一块基板上，e)用于较低频率范围的下面的补件辐射装置(5)的最上面的遮盖补件(5b)同时构成在其上构造的用于较高频率范围的补件辐射装置(7)的基板，f)至少两个在相应馈电补件(5a，7a)中的缝隙结构(11，13)分别通过一根相应的馈电电缆结构(15a，15b)进行馈电。 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).
