Problems solved by technology

However, due to the large space required by the flat-panel antenna, it cannot be used in miniaturized communication products. Therefore, the planar inverted-F antenna is generally used to reduce the size of the antenna. However, the radiation pattern of the planar inverted-F antenna is easily affected by the surrounding objects. Influenced, and then the distribution of its radiation field is limited

Abstract

An antenna device includes a radiation sheet, a ground layer, a dielectric layer and a linear parasitic antenna. The dielectric layer is disposed between the radiation sheet and the ground layer, the radiation sheet and the ground layer are parallel to each other, and the linear parasitic antenna is connected to the ground layer and is perpendicular to the ground layer. In the present invention, a linear parasitic antenna extending parallel to the normal direction of the grounding layer is arranged on the grounding layer to improve the radiation field pattern of the antenna and improve the communication quality of electronic products using the antenna device.
