With the development of Multiple-Input Multiple-Output technologies, researches on radio vortex wave with orbital angular momentum have become active. At the same time, generators of miniaturized planar antennas have become very interesting. Considering multilayer package, we proposed a uniform circle array consisting of four double-layer patch antennas with microstrip backfeeds. The antenna can generate three modes of vortex waves, which works at frequency 7.6GHz with a bandwidth 8.5%. Compared with orbital angular momentum antennas of phased uniform circular array with other cells, this proposed structure can be easily integrated with planar feeding networks and decoupling networks.
