Ceiling-mounted antenna

The invention provides a ceiling-mounted antenna which comprises a PCB, a first radiation portion, a first signal transmission line, a first reflection portion and a second reflection portion. One end of the second reflection portion is fixedly connected with the first radiation portion, the other end of the second reflection portion is fixedly connected with the first reflection portion, the first reflection portion is fixedly installed on the PCB, and the first radiation portion is connected to the PCB through the first signal transmission line. According to the ceiling-mounted antenna, due to the structural design of the first radiation portion, the integral size is reduced, signal processing capacity of the ceiling-mounted antenna is improved, the signal use ratio of a signal source is improved through application of the reflection portions, and the ceiling-mounted antenna is simple in structure and convenient to install, and cannot influence indoor decoration.
