What is the uninterrupted connection between backfire and an

　　The measurement method explained in the previous issue to you, many small partners are still smart, and soon they can understand, but encountered a new problem, that is, antenna backfire. Today, the manufacturer of electronic antenna will reveal to you what is the unremitting connection between backfire and antenna.

　　The backfire of antenna is based on the principle of coherent addition of resonant cavity wave. The resonator is composed of a main reflector, a secondary reflector and a feed. The feed radiation of the slow-wave structure is projected to the main reflector, then reflected back from the main reflector, and then reflected back to the sub-reflector fork, thus forming along its axis in the resonant cavity. Standing wave field". The condition for the formation of the "transit field" is that the spacing between the main reflector and the secondary reflector is an integral multiple of ^/2.Because the resonator formed by the backfire antenna is open, the energy of the open resonator can be radiated to the free space by choosing the appropriate size of each part of the antenna, forming a sharp beam, whose maximum radiation direction is along its axis. Because the radiation direction of the antenna is opposite to that of the feed, the antenna is regarded as "antenna backfire".

　　Antenna can also be involved in these ah, Xiaobian is also a big surprise, but feel worthy of future development of the network focus, after all, this is the most used technology in the future. What else would you like to know if you can consult Xiaobian from the manufacturer of electronic antenna?
