Document Type and Number:
WIPO Patent Application WO/2015/068430
Kind Code:
A1
Abstract:
An antenna comprises: a conductor plane; an island-shaped conductor group which is arranged to face the conductor plane with a dielectric medium therebetween; at least one power feeding part which is connected to one island-shaped conductor of the island-shaped conductor group and transmits power; and a connection part which electrically connects the conductor plane and a first island-shaped conductor that is an island-shaped conductor located on the outermost side of the island-shaped conductor group. Each of island-shaped conductors is capacitively connected to another island-shaped conductor adjacent thereto, the power feeding part is connected at a position other than the center of the island-shaped conductor in the arrangement direction of the island-shaped conductor group, and the connection part is connected at a position inside the first island-shaped conductor by approximately half the width of a second island-shaped conductor, which is an island-shaped conductor located adjacent to the first island-shaped conductor, in the arrangement direction of the island-shaped conductor group from a portion facing the second island-shaped conductor of the edge of the first island-shaped conductor.
