Abstract
This multi-antenna comprises: a substrate; a first antenna element composed of two linear antennas extending from a first feeding point in two different directions, and a second antenna element composed of two linear antennas extending from a second feeding point in two different directions, the first and second antenna elements being arranged to surround one area of the substrate; and a connecting line connecting the first feeding point of the first antenna element and the second feeding point of the second antenna element. The connecting line is connected to the first feeding point of the first antenna element without extending along the bisector of the interior angle formed by the two linear antennas with the first feeding point of the first antenna element at the apex. The connecting line is connected to the second feeding point of the second antenna element without extending along the bisector of the interior angle formed by the two linear antennas with the second feeding point of the second antenna element at the apex.
