The invention discloses a series-feed circularly-polarized antenna normal array. The series-feed circularly-polarized antenna normal array comprises N series-feed circularly-polarized patch antennas,wherein each series-feed circularly-polarized patch antenna is provided with dual ports, a first port and a second port are arranged on each patch antenna and are arranged on a 90-degree central anglearc line, and the N patch antennas are normally arranged at equal distance to form a multi-layer columnar structure along a radiation direction diagram. By the radiation normal array, the gain is improved, meanwhile, only the thickness is increased, while the planar size (normal projection) is not changed, further planar array is facilitated, the gain increment quantity of four unit arrays exceeds 4dB; the radiation efficiency of the normal array is farther higher than radiation of the units, the normal array has better circularly-polarized characteristic than those of the units, left-handed / right-handed circularly-polarized switching still can be easily achieved after arraying, the series-feed unit number N can be freely selected according to a demand, and thus, a feasible scheme for building a three-dimensional array also is provided. A wave absorption material wraps a cable, and the interference of the polarization wave can be effectively eliminated.
