Abstract
The present invention relates to an antenna, which can improve a front-to-rear ratio and cross-polarization isolation without changing a structure of a reflection panel. The antenna includes an antenna element and a reflection panel. The antenna element is disposed on the reflection panel. The antenna further includes a wave-absorbing material layer. The wave-absorbing material layer is disposed on one side of an outer surface, back to the antenna element, of the reflection panel.
