A diversified planar phased array antenna includes a dielectric plate, at least two antenna units, at least one first micro-strip line and a ground layer. Two antenna units formed on the dielectric are coplanar and are connected perpendicular together by the first micro-strip line to form one with vertical field polarization and one with horizontal polarization. Each antenna unit is composed of at least two identical meander line antennas which have unique dual linear polarization property and at least one second micro-strip line connected to the at least two meander line antennas. The first micro-strip line is connected to at least two second micro-strip lines of the two antenna units. Therefore, the planar phased array antenna meets the requirements for spatial diversity, polarization diversity, radiation diversity and frequency diversity, etc. Each antenna unit can be formed by different number of meander line antennas which is determined to be the best for a specific application.
