Abstract
A millimeter wave filtering antenna and a wireless communication device are disclosed. The millimeter wave filtering antenna includes a parasitic unit, a feeding unit and a feeding network. The parasitic unit includes at least one quadrilateral parasitic patch and at least one cross shaped parasitic patch, both of which are nested and combined with each other. The feeding unit includes a feeding patch, and the feeding patch is loaded with a short-circuit patch to form coupling. The feeding network feeds the feeding unit. The wireless communication device includes a millimeter wave filtering antenna according to the present disclosure. The radiation performance of the antenna can not only realize the filtering characteristics with high roll-off and high isolation, but also ensure that no additional insertion loss is introduced.
