Abstract: A planar antenna includes a dielectric layer including a first surface and a second surface on a side opposite from the first surface, an antenna conductor provided on the first surface, a ground conductor provided on the first surface or the second surface, or provided on both of the first surface and the second surface, and a transmission line including a signal line that is connected to the antenna conductor or provided in proximity to the antenna conductor, wherein a dielectric portion of the dielectric layer that is in contact with the signal line has a loss tangent of 0.007 or less at 28 GHz.
