Document Type and Number:
WIPO Patent Application WO/2021/193506
Kind Code:
A1
Abstract:
An antenna device (100) comprises: an implementation board (103) that has a circuit for processing radio signals; dipole antenna elements (101) that are disposed on the implementation board (103) and that receive the radio signals; a first conductor (121) that is parallel to the dipole antenna elements (101); a second conductor (122) that is connected to a first end of the first conductor (121) at an angle greater than zero degree but less than 180 degrees with respect to the first end; and a third conductor (123) that is connected to a second end of the first conductor (121) at an angle greater than zero degree but less than 180 degrees with respect to the second end. At least an end of the second conductor (122) has a parasitic element located in the vicinity of the dipole antenna elements.
