Embodiment Construction
[0033] The accompanying drawings of the present invention are only for illustrative purposes, and should not be construed as limiting the present invention. In order to better illustrate the following embodiments, some components in the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, some known structures and their descriptions in the drawings may be omitted. understandable.
[0034] This embodiment provides a radiation unit, the radiation unit itself does not need to rely on the phase adjustment network of the dielectric substrate, and can adjust the phase of the signal through its feed structure, thereby canceling the phase adjustment network on the dielectric substrate used to connect with it, The radiation index of the radiation unit is excellent and stable, and at the same time, the feed network on the dielectric substrate is minimized.
[0035] like figure 1 As shown, the radiating unit i...

The invention provides a radiation unit, a radiation unit component and an antenna, the radiation unit comprises a radiation surface and two groups of feed structures arranged at the bottom of the radiation surface, and the two groups of feed structures can synthesize a current in a + / -45-degree polarization direction; the at least one group of feed structure comprises a first feed pin and a second feed pin; in at least one group of feed structures, a first length difference exists between the total length of the first feed pin and the total length of the second feed pin, and the first length difference is used for enabling a phase difference to exist between a signal output from the first feed pin and a signal output from the second feed pin at the same time. The radiation unit is based on the length difference of the two feed pins, so that the phase difference exists between signals output from the two feed pins at the same time, that is, the radiation unit does not need other additional phase adjustment networks, and under the condition that the radiation unit is not affected by the design of the phase adjustment networks, the radiation index is excellent and stable, the linearity is optimized, and the performance of the antenna is improved. And the possibility that the radiation performance is deteriorated is greatly reduced.
Description
technical field [0001] The present invention relates to the technical field of antennas, and more specifically, to a radiation unit, components of the radiation unit and an antenna. Background technique [0002] With the large-scale construction of 4G / 5G mobile communication networks, the base station antennas on the site are getting closer and closer, and the industry is trying to reduce the weight of the antennas. As an important part of the base station antenna, the call for weight reduction of the radiation unit is getting higher and higher. At the same time, in order to cope with the tense situation of raw materials in the industry, how to improve the production efficiency of the radiation unit as much as possible while meeting the low-carbon requirements is also a top priority. [0003] One of the conventional types of radiating elements is the one-piece stamping and forming radiating element, which is low in cost, light in weight, and has a large degree of design fre...
