Abstract

The invention provides a radiation unit. The radiation unit comprises one group or two groups of mutually-orthogonal half-wave vibrators, feed supporting columns and coupled balun feed probes; symmetrically-distributed metal sheets are arranged on the two arms of the half-wave vibrators, and one sunk feed supporting column is arranged below each metal sheet; the feed supporting columns are connected with corresponding metal sheets and lug bosses respectively; the symmetric center of the half-wave vibrators coincide with the axis corresponding to a columnar structure formed by the feed supporting columns in a surrounding way; a wing-shaped structure with a capacitive loading effect is arranged on the metal sheets; the balun feed probes are arranged in the feed supporting columns and are bent in the crossing place and staggered up and down; and the adjacent top angles of the two metal sheets of each group of the half-wave vibrators are electrically connected through the balun feed probes. The invention also provides corresponding antenna and the half-wave vibrators. The height of the antenna is lowered while the volume of the base station and the micro base station are reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a half-wave oscillator, a radiation unit and an antenna. Background technique [0002] At present, the die-casting oscillators used in base station antennas are all classic half-wave oscillators with a quarter-wavelength height; with the rapid development of the communication industry, there are more and more urgent requirements for the miniaturization of antennas, and reducing the height of the oscillators is also That is, the contribution of reducing the thickness of the antenna to reducing the volume of the antenna is obviously the largest. In addition, the microstrip antenna can solve the height problem of the existing antenna, but the bandwidth of the microstrip antenna is limited, and the isolation and cross-polarization ratio cannot meet the requirements of the existing base station antenna. Contents of the invention [0003] In order to solve the above technical ...
