PROBLEM TO BE SOLVED: To cope with miniaturization of a communication antenna and a communication device mounting it, to suppress interference between antennas, and to secure communication performance of the communication antenna even if it is buried in a wall or inside another large device.SOLUTION: A communication antenna comprises a first element surface of which one end is connected with a feeding point. The other end of the first element surface further comprises a second element surface that is orthogonal to the first element surface and connected with an edge in the extending direction of the first element surface. In addition, the communication antenna further comprises a second communication antenna that is a loop-shaped antenna and its loop surface is orthogonal to the first element surface and arranged in parallel to the second element surface. Furthermore, in a communication device comprising such a composite communication antenna, the first element surface of a first communication antenna is arranged between the loop-shaped second communication antenna and an operation/display unit of a control unit. |
