Miniaturization short wave broadband omnidirectional high elevation communication antenna

Abstract

The invention discloses a miniaturization short wave broadband omnidirectional high elevation communication antenna which comprises eight bases which are arranged into two rows and four columns, each two bases which are arranged in the same row and on the outer side and the inner side respectively are connected with each other through a transverse vibrator I, and each base is provided with a vertical vibrator I. Load assemblies for resistance loading are arranged among the four vertical vibrators I which are arranged on the inner side and in the same row, the four vertical vibrators I which are arranged on the outer side and in the same row are continuously provided with vertical vibrators II, two transverse vibrators II are arranged among each four vertical vibrators II in a cross mode, and impedance transformers are arranged on cross points of the transverse vibrators II. The antenna is simple in structure, convenient to produce, small in size, and capable of being conveniently supported in a small place, achieves a high elevation of a radial direction picture when at low and medium frequency, is suitable for middle-near distance communication, achieves a low elevation of the radial direction picture when at high frequency, can meet communication requirements of a remote distance, and meanwhile meets communication requirements of remote, middle and near distances.

Description

technical field [0001] The invention relates to the technical field of short-wave communication, in particular to a miniaturized short-wave broadband omnidirectional high-elevation angle communication antenna in this field. Background technique [0002] Although the modern communication technology is very complete, the traditional short-wave communication still has its irreplaceable advantages, and the short-wave antenna is a necessary equipment for short-wave communication. The performance of the antenna largely determines the performance of the communication system. Although human technology is changing with each passing day, there has been no major progress in short-wave antenna technology for decades. The conflicts between the large geometric size, high gain, omnidirectionality, and radiation elevation angle of the short-wave antenna are difficult to be resolved or well balanced.

AI Technical Summary

Problems solved by technology

The disadvantages are: the size is long, the antenna body is generally about 30 meters to 40 meters long, and a support rod is required, the communication distance is related to the height, directional communication, and not omnidirectional

The disadvantages are: the efficiency is too low, the pass rate is low, it is not omnidirectional, the reliability is poor at low frequencies, and there is a dead point in the tuner
