Abstract

The invention relates to radio communication equipment and discloses a P-waveband high-power broadband element antenna which comprises an antenna element, a tuning post, a tuning cavity, a vertical post, a feed seat and a base seat, wherein a coaxial feed connector is installed on the antenna base seat and is connected with a signal transmitting source, and a balance feed structure in the form of a grid plate is arranged between the coaxial feed connector and the element. The power capacity is 3 times of that of the conventional coaxial wire balance feed, the standing wave bandwidth of the element antenna is broadened, and the bandwidth on a carrier with the standing-wave ratio smaller than 1.3 can reach 20% which is 2 times of the bandwidth of the conventional element antenna structure. The invention solves the problems of narrow bandwidth, small power capacity and the like of the traditional element antenna and has the advantages of broad band, compact structure, high power resistance and the like.

Description

technical field [0001] The invention relates to radio communication equipment, in particular to a P-band high-power broadband dipole antenna. Background technique [0002] The antenna vibrator is a component on the antenna, which has the function of guiding and amplifying electromagnetic waves, so that the electromagnetic signal received by the antenna is stronger. The antenna vibrator is made of metal with good conductivity. Some vibrators are rod-shaped, and some have more complex structures. Generally, many vibrators are arranged in parallel on the antenna. [0003] At present, known dipole antennas have disadvantages such as narrow bandwidth and small power capacity. [0004] At present, there are methods to widen the bandwidth such as parallel resonant circuit loading in China, but the structure is relatively complicated and the power capacity is limited. [0005] Contents of the invention [0006] In order to solve the problems of narrow bandwidth and small power...
