摘要：
A planar antenna is disclosed. The planar antenna includes: a radiator element having a wideband resonant characteristic; and a parasitic element having a planar shape. The parasitic element has a first side, a second side, a third side and a fourth side. Each of the first side and the second side is parallel to a direction of an electric current to be excited in the radiator element. The first side is located closer to the radiator element than the second side is. The first side is shorter than the second side. The third side connects one ends of the first side and the second side. The fourth side connects the other ends of the first side and the second side. A region between the third and fourth sides tapers in a direction from the second side toward the first side.
