ANTENNA APPARATUS |
| 摘要 |
An antenna apparatus has a dielectric substrate and conductors. The antenna apparatus includes an antenna element which is arranged on a main surface of the dielectric substrate and has directivity ahead of the main surface, and a directional characteristic control member which includes a sidewall part which projects ahead of the main surface on at least one side of directivity of the antenna element with respect to the antenna element, and a roof part which projects in a direction of the antenna element from the sidewall part at a predetermined angle of more than 70° and less than 120° with respect to the sidewall part so that orthogonal projection to the main surface does not reach the antenna element, to reflect or absorb radio waves. |

1. An antenna apparatus which has a dielectric substrate and conductors, characterized in that the antenna apparatus comprises:
an antenna element which is arranged on a main surface of the dielectric substrate and has directivity ahead of the main surface, and a directional characteristic control member which includes a sidewall part which projects ahead of the main surface on at least one side of directivity of the antenna element with respect to the antenna element, and a roof part which projects in a direction of the antenna element from the sidewall part at a predetermined angle of more than 70° and less than 120° with respect to the sidewall part so that orthogonal projection to the main surface does not reach the antenna element, to reflect or absorb radio waves. |
