Title:
ANTENNA DEVICE AND MOBILE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2020/209074
Kind Code:
A1
Abstract:
Provided is an antenna device that has unidirectional directivity, and is capable of achieving reduction in size and thickness and band widening. The antenna device is provided with: a radiation part 11 that has a plate-shaped first antenna element 13 having a first cutout section 21, a second antenna element 14 that is disposed so as to face the first antenna element 13 and has a smaller width than the width of the first antenna element 13, a power feeding part 15, and a resistance element 22; and a reflection plate 12 that is disposed so as to face a rear surface of the radiation part 11. The power feeding part 15 is connected between a first outer end portion of the first cutout section 21 and the second antenna element 14, and the resistance element 22 is connected between a second outer end portion of the first cutout section 21 and the second antenna element 14. This configuration makes it possible to achieve reduction in size and thickness and band widening of the antenna having unidirectional directivity.
