The feeder 40 is electrically connected to the feeder probe 30 and the groove bottom of the metal groove body 20 respectively.

Among them, the working principle of the embodiment of the present invention can be referred to the following expression:

Since the antenna dielectric body 10 is located in the metal groove body 20, when the antenna module 100 is radiating, due to the blocking effect of the groove bottom and the side walls of the metal groove body 20, the antenna module 100 can only move along the metal groove body 20. Radiation in the opening direction of the groove body 20 avoids radiation to the groove bottom and side walls of the metal groove body 20. That is, the structure of the antenna module 100 described above may cause most or all of the radiation energy of the antenna dielectric body 10 to be concentrated in Facing the opening direction of the metal groove body 20, the radiation distance of the antenna module 100 is longer and the radiation performance is better.

At the same time, because the antenna module 100 also includes the feeder probe 30, the antenna module 100 may also include a feeder 40, and the feeder 40 can be electrically connected to the feeder probe 30 and the groove bottom of the metal groove body 20, respectively. The power feeding to the antenna module 100 is realized. In this way, the feeding through the feeding probe 30 can improve the reliability of the feeding of the entire antenna module 100. At the same time, the feeding probe 30 is inserted into the antenna dielectric body 10, so that the radiation energy of the antenna dielectric body 10 can be increased. Most or all of them are concentrated toward the opening direction of the metal groove body 20, so that the radiation performance of the antenna module 100 can be further enhanced.

The processing steps of the metal groove body 20 may include: obtaining a metal block, and processing the metal block so that a groove is recessed on the metal block, thereby obtaining the metal groove body 20. The cross-sectional shape of the metal groove body 20 may be a circular ring or a rectangular ring.

Among them, the antenna module 100 in the embodiment of the present invention may also be referred to as a dielectric resonant antenna module. In addition, a through hole may be provided on the groove bottom of the metal groove body 20, and the feed probe 30 can be inserted into the antenna dielectric body 10 through the through hole, and the feed probe 30 does not contact the metal groove body 20. In this way, the feeding probe 30 can be insulated from the metal groove body 20.

The specific shape of the antenna dielectric body 10 is not specifically limited herein. For example, the shape of the antenna dielectric body 10 may be a cylinder or a rectangular column. Correspondingly, the shape of the metal groove body 20 may also be adapted to the shape of the antenna dielectric body 10. When the shape of the antenna dielectric body 10 is a cylinder, the shape of the metal groove body 20 may also be a cylinder. ; When the shape of the antenna dielectric body 10 is a rectangular column, the shape of the metal groove body 20 may also be a rectangular column.
