Example Embodiment

[0021] The present invention provides a rotating system for an H-plane array shortwave logarithmic three-dimensional array antenna. In order to make the purpose, technical solutions and effects of the present invention clearer and clearer, the present invention is further described below in detail. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0022] Logarithmic Periodic Antenna (LPDA) is a broadband antenna with excellent electrical characteristics. Its main electrical parameters such as input impedance, pattern, and gain coefficient are approximately independent of frequency, and its electrical characteristics are paired with the operating frequency. number-period relationship, that is, at any frequency f 0 possessed characteristics will be in all f n =τf 0 repeats at the frequency of , where f 0 ->τnf 0 is called a period (τ is the period rate, n=±1, 2, 3, ...

Abstract

The invention discloses a rotating system of an H-face array short wave logarithm three-dimensional array antenna. The antenna comprises a support and a plurality of log periodic antenna units which are erected on the support, are arrayed according to preset included angle degree and are distributed in a sector shape. The support is erected on a vertical tower mast. The rotating system comprises a turning mechanism and a rotating mechanism. The turning mechanism is arranged at the top end of the tower mast, is movably connected with the support and is used for adjusting the elevation angle of the antenna. The rotating mechanism is arranged at the bottom end of the tower mast. Horizontal rotating of the antenna is achieved by the fact that the rotating mechanism drives the tower mast to rotate. According to the rotating system, the matched rotating system is arranged for a novel antenna system, the antenna of the rotating system can be horizontally adjusted by 360 degrees in a full-angle-elevation-angle through the arranged turning mechanism and the arranged rotating mechanism, and accordingly the antenna has great signal transmitting and receiving performance after angle adjusting, and the performance of the H-face array short wave logarithm three-dimensional array antenna is achieved to the maximum degree.

Description

technical field [0001] The invention relates to the technical field of communication antennas, in particular to a rotating system of an H-plane array short-wave logarithmic three-dimensional array antenna. Background technique [0002] Traditional domestic short-wave large-scale antenna systems are mainly broadband curtain antennas, such as figure 1 and 2 shown. The broadband curtain antenna is an antenna array composed of multi-layer full-wave or half-wave dipoles. The horizontal pattern is controlled by the number of antenna elements in each layer, and the vertical pattern is controlled by the number of layers of element antennas and the separation distance of the lowest layer antenna. height control. Its advantages are wide frequency band range, high power and long propagation distance. However, the disadvantages of broadband curtain antennas are also obvious, mainly including: 1. Large area and harsh terrain requirements; 2. The main body of the antenna is high and t...
