Background
In the related art, satellite communication is more emphasized in directional communication than cellular communication, and the requirements for indicators such as direction and gain are higher. In addition, since the communication satellite is far from the ground, the attenuation of the space path is large, and the communication satellite also has the circular polarization characteristic of left hand or right hand, the satellite antenna on the electronic equipment such as a mobile phone needs to have the same circular polarization characteristic, so that the polarization loss is reduced, and the performance of satellite communication is improved. However, since the radiator of the satellite antenna on the electronic device is generally disposed on the metal housing of the electronic device, it is difficult for the radiator of the satellite antenna to form a field component in the thickness direction of the electronic device, so that it is difficult for the radiator to form circular polarization characteristics in the radiation direction at the top of the electronic device, and thus there is a problem that the satellite antenna on the electronic device has poor communication performance.

The feed source is electrically connected with the first radiator through the first feed point or the second feed point so as to enable the circular polarization characteristic of the satellite antenna to be consistent with that of a communication satellite.
In the embodiment of the application, whether the feed source is electrically connected with the first radiator through the first feed point or is electrically connected with the first radiator through the second feed point can be determined based on the working frequency band of the satellite antenna, so that the circular polarization characteristic of the satellite antenna is consistent with the circular polarization characteristic of the communication satellite, and the aim of improving the communication performance of the satellite antenna is fulfilled.
