Abstract
A dual-band multi-mode array antenna is provided, including an antenna substrate with antenna units each of which having a feeding via; and a conductive substrate connected to the antenna substrate to form an angle in between. The conductive substrate has a symmetric feeding network disposed on a surface of the conductive substrate; and a first ground portion disposed on another surface of the conductive substrate. The symmetric feeding network and the first ground portion are electrically coupled to each of the antenna units through the feeding vias. Moreover, the antenna units are electrically coupled in parallel.
