| 发明名称 | Antenna structure and multi-beam antenna array using the same | ||
| 摘要 | An antenna structure comprises a substrate, a first antenna unit and a second antenna unit. The substrate comprises a first surface and a second surface opposing the first surface. The first antenna unit is disposed on the first surface, and comprises at least a first slot with a wider inside and narrower outside at the edge of the first antenna unit. The second antenna unit is disposed on the second surface, and is connected to the first antenna unit through a hole in the substrate. The radius of the at least one first slot is one-fourth the wavelength of the central frequency of the antenna structure. | ||
