Provided is a planar antenna capable of coping with a wide frequency band that is a relatively high frequency band of the degree of 6 GHz. The planar antenna includes a slot formed in a flat conductor, the slot including: a first slot extending in a first direction between a first power supply point and a second power supply point; a second slit extending in a second direction different from the first direction from an end portion of the first slit in the first direction; a third slit extending in a fourth direction opposite to the second direction from an end of the first slit in a third direction opposite to the first direction, and reaching an open end open in the fourth direction; and a J-shaped slit extending in a J-shape from an end portion of the second slit in the second direction to an open end open in the first direction, the slit width at the open end of the J-shaped slit being wider than the slit width at the end portion of the second slit in the second direction.
本申请提供一种能够应对至6GHz程度的比较高的频带的宽频带的平面天线。平面天线具备形成于平坦的导体的缝隙,所述缝隙包括:第一缝隙,在第一供电点与第二供电点之间沿第一方向延伸;第二缝隙,从所述第一缝隙的所述第一方向的端部沿与所述第一方向不同的第二方向延伸;第三缝隙,从所述第一缝隙的与所述第一方向的朝向相反的第三方向的端部沿与所述第二方向的朝向相反的第四方向延伸,并到达向所述第四方向开放的开放端;及J字缝隙,从所述第二缝隙的所述第二方向的端部呈J字状延伸至向所述第一方向开放的开放端,所述J字缝隙的开放端处的缝隙宽度比所述第二缝隙的所述第二方向的端部处的缝隙宽度宽。
