  • Antenna device and wireless communication apparatus
    Patent number: 9184509
    Abstract: The antenna device includes a first antenna 11 that includes a first ground terminal 12; a second antenna 18 that includes a second ground terminal 20; a ground conductor 28 to which the first antenna 11 is connected through the first ground terminal 12 and the second antenna 18 is connected through the second ground terminal 20; and a phase shifter 24 that controls a phase difference between a first current ie1 and a second current ie2. The phase shifter 24 controls the phase difference between the first current ie1 and the second current ie2 so that the first current ie1 and the second current ie2 have components to cancel each other.
