Omnidirectional short-wave high-gain antenna array suitable for use over near, middle and far communication distances

Abstract

The invention provides an omnidirectional short-wave high-gain antenna array, which mainly solves the problems of the short-wave station antenna in prior arts including large occupied area, small quantity and low gain. The omnidirectional short-wave high-gain antenna array comprises vertically-polarized antennae and horizontally-polarized antennae, wherein the vertically-polarized antennae are omnidirectional circular array antennae composed of a plurality of pairs of corner reflector antennae (4) or log-periodic antennae (61) and a supporting rod; and the horizontally-polarized antennae comprise a low-frequency horizontally-polarized antenna (3) and a high-frequency horizontally-polarized antenna (5). The low-frequency horizontally-polarized antenna (3) is composed of two pairs of binary orthogonal horizontally-polarized branched cage type array antennas (7), and the high-frequency horizontally-polarized antenna (5) is composed of a plurality of pairs of binary horizontally-polarized branched cage type array antennas (51) with same structures. The low-frequency horizontally-polarized antenna (3) and the high-frequency horizontally-polarized antenna (5) are fixed on the surface and the circumference of the omnidirectional circular array antenna, respectively. The omnidirectional short-wave high-gain antenna array has the advantages of small occupied area and high antenna gain and can be used as a communication antenna of near, middle and far distances.

[0002] Short-wave is one of the most important means for civilian and military use to achieve short-, medium-, and long-distance communications. With the rapid development of information technology, the electromagnetic environment is becoming more and more harsh. In order to resist interference and achieve reliable short-wave communication, it is necessary to increase the short-wave antenna. Gain, in addition to the use of high-gain unit short-wave antennas, but the most effective method is to use unit high-gain short-wave antenna arrays, but the existing technology is used for long-distance horizontal in-phase antenna arrays with a very small number, and most of them use The short-wave communication antennas for near, medium and long distances are multi-unit antennas, such as one-unit cage antennas, branch cage antennas, biconical monopole antennas, three-wire and four-wire short-wave broadband antennas loaded with lossy components, and sector cone antennas. And umbrella cone antennas, these antennas not only have low gain, but also occupy a large area in the antenna field of the transceiver station, and the number of antennas is small. In addition, due to the high cost of land, it is difficult to find a large site to install and erect antennas in the new antenna field

It is impossible to provide users with multiple short-wave broadband antennas in a limited space
