Abstract

An antenna system, a communication device, and a communication system. The antenna system includes an antenna apparatus. The antenna apparatus includes a radiating element array and a reflection plate. The radiating element array is disposed on a first side of the reflection plate. The reflection plate further has a second side opposite to the first side. The reflection plate includes a plurality of reflection plate through holes. Space on the two sides of the reflection plate is connected through the plurality of reflection plate through holes. The antenna system further includes a blade. The blade is located on one side of the antenna apparatus, and is disposed opposite to the plurality of reflection plate through holes. The solutions provided help reduce impact of wind load on the antenna system, and improve performance of the antenna system.
