PLANAR ARRAY ANTENNA AND WIRELESS COMMUNICATION MODULE

Provided is a planar array antenna with which band widening is possible. The planar array antenna includes a plurality of unit cells (50) disposed in one or two dimensions. Each of the unit cells (50)comprises: a radiation part (51) that includes a radiation conductor (11) and a first ground conductor layer (13) that is disposed separated from the radiation conductor (11) and has a first slot (13c); and a power supply unit (52) that includes the strip conductor (14). The strip conductor (14) has a first end part (14c) that is supplied with power from outside, and a second end part (14d) thatis separated in the length direction from the first end part. The distance between the first end part (14c) and the first ground conductor layer (13) differs from the distance between the second end part (14d) and the first ground conductor layer (13). 本发明提供能够实现宽带化的平面阵列天线。平面阵列天线包括呈1维或2维配置的多个单位元件(50)。各单位元件(50)包括辐射部(51)和供电部(52)，该辐射部(51)包括辐射导体(11)和与辐射导体(11)间隔地配置、具有第1槽隙(13c)的第1地导体层(13)，该供电部(52)包括带状导体(14)和带状导体(14)，带状导体(14)具有从外部
