Description
Technical Field
The utility model relates to the technical field of antennas, in particular to a buried antenna and a broadband intermediate frequency antenna.
Background
Buried antennas are a widely used form of antenna and are also an important component of underground communication systems. Because the underground medium is soil instead of air, for better signal transmission, the medium frequency signal can be used, however, the medium frequency antenna has large size and large occupied area, is very unfavorable for laying, has a narrow working bandwidth, and cannot simultaneously meet the communication systems with different working frequencies.

Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. The specific embodiments described herein are only for the purpose of illustrating the technical solution of the present utility model and are not to be construed as limiting the utility model.
An integrated broadband intermediate frequency buried antenna for tunnels in an embodiment of the present utility model is shown in fig. 1 and 2. The buried antenna in the embodiment is of a cylindrical cage structure and consists of a horizontal vibrator arm 2, a vertical circular ring 3 and a supporting rod 4. The tunnel peripheral medium 1, in this example coal, is selected to have a depth of 20m.
In the embodiment, the antenna material is made of aluminum metal, is not easy to oxidize or corrode, and is low in cost. 8 vibrator arms are horizontally arranged in parallel, the length is 20m, the two adjacent included angles are 45 degrees, the number of the vibrator arms can influence the standing-wave ratio of the antenna, and the more the number is, the smaller the standing-wave ratio is; the length of the dipole arm determines the frequency of the antenna, the longer the length the lower the frequency. The 2 rings are vertically arranged at the two ends of the vibrator arm, the radius is 1m, the radius of the rings can influence the standing-wave ratio of the antenna, and the smaller the radius is, the lower the standing-wave ratio is. The 2 spinal branch vaulting poles are placed inside two rings, intersect with the ring, length 2m, at bracing piece central point feed, use coaxial line feed, connect the matching network simultaneously, coaxial line's outer ground connection. The antenna is wrapped by the tunnel, the antenna and the tunnel are conformally placed, the antenna has a certain supporting effect on the tunnel, the safety of workers can be protected at the time of crisis, and the standing wave ratio of the antenna at the frequency of 300KHz-3MHz can be smaller than 1.5 by the matching network connected with the antenna, so that the bandwidth is high. The standing wave of the antenna without the matching network is shown in fig. 3.
The foregoing description of the preferred embodiments of the present utility model has been presented only in a detailed and specific manner, but is not to be construed as limiting the scope of the utility model. It should be noted that modifications, improvements and substitutions can be made by those skilled in the art without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
