Power divider network and antenna structure
A power divider network includes a cover plate, a reflection plate, a support component, and a feed line. The reflection plate is arranged separately from the cover plate. A first surface of the reflection plate is a reflection surface. A plurality of connectors protrude from a second surface of the reflection plate opposite to the reflection surface. The plurality of connectors are arranged at intervals. The plurality of connectors are coupled with the cover plate and divide the space between the reflection plate and the cover plate into at least one hollow chamber. The support component is at least partially arranged in the hollow chamber. The feed line is arranged in the hollow chamber and mounted at the support component.
