Abstract
A wireless communication device and a wireless communication method capable of improving the directivity of an antenna in a desired direction for a low cost are provided. According to one example embodiment, a wireless communication device includes: a printed board having a substrate surface; a ground plane having a plate shape that is disposed on the substrate surface, connected to the ground potential, and is parallel to the substrate surface; an omnidirectional antenna that is disposed alongside the ground plane on the substrate surface in one direction in a plane parallel to the substrate surface, and is caused to emit radio waves by being supplied with power; and a parasitic antenna that is disposed away from the ground plane in a direction perpendicular to the substrate surface and resonates with the omnidirectional antenna supplied with power.
