Embodiment Construction

[0031] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0032] Here, a spiral-loaded high-gain omnidirectional monopole antenna will be designed based on 0.75 times the wavelength of the same-directional current, and the present invention will be described in detail with corresponding drawings. It should be noted that the preferred implementation examples described here are only used to illustrate and explain the present invention, and are not used to limit or limit the present invention.

[0033] The spiral-loaded high-gain omnidirectional monopole antenna of the present invention is provided with a circular floor 9 , a spiral-loaded radiator and a plurality of short conductor piles 7 . Its material is made of good metal conductors, such as copper (pure copper), alloy copper (such as brass), and pure aluminum. The spiral-loaded radiator is arranged at the center of the cir...

Abstract

A helical loading high-gain omnidirectional monopole antenna is provided with a circular floor, a helical loading radiator and a plurality of short conductor piles, the helical loading radiator is arranged in the center of the circular floor, and a plurality of conductor short piles are provided. The piles are evenly distributed on the circular floor around the helical loading radiator. The helical loading radiator consists of an upper conductor section, a helical section and a lower conductor section. The upper conductor section is L-shaped and connected to the upper end of the helical section, and the lower conductor section is Invert the L shape and connect with the lower end of the helical segment. Using the method of floor-loading circularly arranged metal columns, the monopole antenna achieves high gain, omnidirectionality, wide E-plane beam, low side / backlobe and high-efficiency radiation in a narrow band.

Description

technical field [0001] The invention relates to a mobile communication base station and terminal antenna equipment and technology, in particular to a spiral-loaded high-gain omnidirectional monopole antenna and its technology. Background technique [0002] The antenna is the air interface connecting the terminal equipment and the network in the wireless communication system, so it is one of the most critical components of the whole system, and its performance directly determines the communication quality. In a mobile communication system, due to the mutual mobility of the transmitting station and the terminal equipment, both parties need to install omnidirectional antennas to ensure that they can still communicate when they are in any orientation relationship. Therefore, omnidirectional antennas have a wide range of application requirements and have received a lot of research. Among them, the single / dipole antenna is the earliest invented, the simplest structure, and the mos...
