Abstract
An antenna element includes a body including laminated insulator layers, a first ground conductor, and a radiation conductor overlapping the first ground conductor along a first direction from the first ground conductor. Guard ground conductors are provided in the body along the first direction to surround the radiation conductor. The guard ground conductors include second ground conductors electrically interconnected, and one or more first interlayer connection conductors piercing the insulator layers. The second ground conductors are shaped to not make a circuit of the radiation conductor, and are positioned at multiple positions relative to up-down directions. The second ground conductors each have an overlapping portion that overlaps the second ground conductor positioned adjacent to the overlapping portion in an upward or downward direction, and a non-overlapping portion that does not overlap the second ground conductor positioned adjacent to the non-overlapping portion in the upward or downward direction.
