Abstract:
1. An antenna comprising: a ground plate which is planar; a first power feed element which is disposed separately from the ground plate by a prescribed distance and which is formed in a prescribed shape; a second power feed element which is branched from the first power feed element; a first parasitic element which is planar and which is formed in a prescribed shape; a second parasitic element which is disposed to face the second power feed element; a first shortcircuit part which electrically connects the first parasitic element and the ground plate; a second shortcircuit part which connects the second parasitic element to the ground plate; and a power feed part which is electrically connected with the first power feed element, wherein the first power feed element and the first parasitic element are disposed in parallel in part with each other, and the first power feed element and the first parasitic element have multiple resonances by electro magnetic coupling.
