description To provide a circular polarization shared planar antenna capable of being properly compatible with a high frequency and achieving size and weight reductions.SOLUTION: The circular polarization shared planar antenna includes: a straight polarization planar antenna 2, in which each of two feed elements 232b, 216b transmitting and receiving two polarization signals orthogonal to each other is arranged in a matrix manner and in which an upper layer feed element substrate 232 and a lower layer feed element substrate 216 are laminated; and a polarization converter 3 which is laminated on the radiation plane side of the straight polarization planar antenna 2 and formed from meander line polarizers 312, 322, 332, 342, 352 and which converts one of the two polarization signals into a left-handed circular polarization and converts the other into right-handed circular polarization.SELECTED DRAWING: Figure 1 【課題】高い周波数に適正に対応可能で、かつ、小型軽量化が可能な円偏波共用平面アンテナを提供する。【解決手段】互いに直交する２つの偏波信号を送受信する２つの給電素子２３２ｂ、２１６ｂがそれぞれマトリクス状に同配列された、上層給電素子基板２３２と下層給電素子基板２１６が積層された直線偏波平面アンテナ２と、直線偏波平面アンテナ２の放射面側に積層され、メアンダーラインポラライザ３１２、３２２、３３２、３４２、３５２で構成されて、２つの偏波信号の一方を左旋円偏波に変換し他方を右旋円偏波に変換する偏波変換器３と、を備える。【選択図】図１
