Description

Technical Field

[0001] The utility model relates to the technical field of communications, in particular to a gain antenna feed fixing bracket with good heat dissipation effect. Background Art

[0002] Gain is the ratio of the maximum radiation intensity in a specified direction to the maximum radiation intensity of the antenna, that is, the antenna power amplification factor. Under normal circumstances, the strength of the gain will interfere with the antenna's ability to radiate or receive wireless signals. In other words, under the same conditions, the higher the gain, the longer the wireless signal propagation distance. The feed source is an important component of antennas such as reflector antennas or lens antennas. Its function is to radiate the RF power from the feed line to the reflector or lens in the form of electromagnetic waves, so that it produces a suitable field distribution at the aperture to form the required sharp wave beam or shaped beam; at the same time, the power leaking out of the edge of the reflector or lens is minimized in order to achieve the highest possible gain.

[0003] When existing gain antennas are actually used, high-intensity reception or transmission of signals will cause the feed source to overheat, affecting the actual use of the antenna and resulting in poor quality of the received or transmitted signals.

[0004] Therefore, we propose a gain antenna feed fixing bracket with good heat dissipation effect to solve the above-mentioned problems. Utility Model Content

While the cooling water flows in the cooling pipe, it also cools the air in the shell. Through double cooling, the heat dissipation effect is enhanced, which effectively avoids overheating of the gain antenna and ensures the quality and effect of the signal.
