Abstract
An antenna device and a communication device capable of changing over polarization characteristics of an antenna to improve transmission capacity in various kinds of polarization environments and used configuration by preventing reduction of the communication capacity for a reception signal degrading or varying depending on momentarily changing polarization conditions between a base station and a terminal. The antenna device (110) includes a plurality of first antenna elements (111,112) for a first polarizing direction, a second antenna element (121) provided in the direction orthogonal to the first polarizing direction, a plurality of switches (131,132) for switching connection between the plurality of first antenna elements (111,112) and the second antenna element (121), and power supply parts (141,142) respectively provided on the plurality of first antenna elements (111,112).
