The invention discloses a high-isolation low-profile dual-polarized antenna applied to a WLAN. The antenna is composed of a single-sided microstrip circuit board and a grounding structure board with arectangular air back cavity. Antenna working bandwidth expansion is realized, meanwhile, the structural advantages and the radiation performance of the single-layer microstrip antenna are maintained,the innovative structural form of the single-layer microstrip and the back cavity is used, the microstrip patch antenna array which has the advantages of being simple in structure, low in profile, capable of being integrated with a feed network easily and the like and conveniently achieve high efficiency and low profile is designed. 本发明公开一种应用于WLAN的高隔离度低剖面双极化天线，由单面微带电路板及带有矩形空气背腔的接地结构板两部分组成,拓展了天线工作带宽，同时维持了单层微带天线在结构上的优势和辐射性能，使用具有创新形式的单层微带加背腔的结构形式，设计出具有结构简单、剖面低、易与馈电网络一体化设计等方面的优点，便于实现高效率、低剖面的微带贴片天线阵。
