Document Type and Number:
WIPO Patent Application WO/2018/179814
Kind Code:
A1
Abstract:
The present invention provides an antenna device that can be miniaturized while suppressing a drop in antenna gain. A band III capacity loaded element 8 is made up of one metal sheet component and has a side part 8a and a top part 8b. The side part 8a is a flat surface perpendicular to a base. The side part 8a is shaped so that the height with respect to the base increases from the front toward the rear. The top part 8b is a portion that is bent from the upper end of the side part 8a. The upper edge of the side part 8a and the left edge of the top part 8b come in contact with each other. The top part 8b is perpendicular to the side part 8a. The top part 8b has a smaller angle with respect to the base than the side part 8a. The right edge of the top part 8b is the outer edge of the band III capacity loaded element 8.
