Reader antenna applicable to intensive container

The invention relates to a reader antenna applicable to an intensive container. The reader antenna comprises a first circular coil and a second circular coil; the first circular coil and the second circular coil are consistent in winding directions; the two end heads of the first circular coil are connected with the two end heads of the second circular coil through a first connecting wire and a second connecting wire; a feeding point is arranged on the first connecting wire; and the feeding point is used for being electrically connected with a reader through a coaxial cable. The antenna disclosed in the invention, by adopting a circular polarization mode, can realize matching of linearly polarized tag antennas in an intensive environment, so that the antenna is high in reading stability, high in reading speed, high in reading efficiency, uniform in signal range and relatively high in gain, simple in structure, low in construction cost, uniform in signals, low in requirement on RFID tagreading-writing power, a
