Abstract:
1. An antenna apparatus comprising: two pattern antennas made of a metal conductor arranged, on a first surface of a dielectric substrate, side by side in an area close to a ground conductor layer, wherein each of the pattern antennas includes: wherein the two pattern antennas are formed in shapes substantially line symmetric with each other, and a portion of the radiation element is made to be a mutual coupler that extends in such a manner as to be substantially in parallel with and adjacent to a symmetry axis of the two antennas, wherein an end of the mutual coupler nearer to the ground conductor layer is connected to the feed coupler and a portion of the radiation element winding and extending from the other end of the mutual coupler is made to have an open end near the ground conductor layer, and wherein the respective mutual couplers of the two pattern antennas are capacitively coupled with each other.
