Abstract
An antenna module is provided. The antenna module includes a reflective superstrate, an antenna substrate, an antenna and a reflective pattern. The antenna is disposed on the antenna substrate. The reflective pattern is formed on the reflective superstrate, wherein a reflection gap is formed between the reflective superstrate and the antenna substrate. The reflective pattern provides a first reflection phase angle, the antenna substrate provides a second reflection phase angle, the first reflection phase angle includes a first determined phase angle Δ, the first determined phase angle Δis not 0°, the first reflection phase angle is about −(180°−Δ), the second reflection phase angle includes a second determined phase angle Δ, the second reflection phase angle is about −(180°−Δ), a dimension of the reflection gap is directly proportional to a total predetermined phase angle Δ=Δ+Δ, and the total predetermined phase angle is between 0°˜90°.
