Abstract: An antenna apparatus is provided with a first antenna element, a second antenna element, a first ground element, a first ground plane and a second ground plane each formed by a conductive pattern. The first antenna element and the second antenna element are electrically connected by a first through-hole, and also form a first capacitive coupling portion in which they partially overlap across a substrate and are capacitively coupled. Such a configuration enables the antenna apparatus to be realized at low cost, since an antenna can be formed with only a substrate and conductive patterns, without requiring additional elements such as sheet metal. The antenna apparatus also can be reduced in profile and size, since only the conductive patterns are formed on a first surface and a second surface of the substrate, and there are no members that project significantly from the plane of the substrate.

Abstract: A communication module of the present application includes a first antenna element 12, a second antenna element 13, and a ground portion 14. The first antenna element 12 and the second antenna element 13 can transmit and receive radio signals. The ground portion 14 is provided between the first antenna element 12 and the second antenna element 13 and can suppress electrical interference between the first antenna element 12 and the second antenna element 13. The ground portion 14 is a ground potential. Thus, the unwanted radio waves leaking from the first antenna element 12 and the second antenna element 13 are grounded electrically, so that the degradation of isolation can be suppressed.
