A Vertically Polarized Omnidirectional Antenna

Abstract

The present invention discloses a vertical polarized omnidirectional antenna. The vertical polarized omnidirectional antenna comprises a radiation fin, a metal support chip, a metal chassis and a coaxial cable. The metal support chip is arranged between the radiation fin and the metal chassis, the core line of the coaxial cable is electrically connected with the center of the radiation fin, and the outer conductor of the coaxial cable is electrically connected with the metal chassis; the radiation fin is provided with top radiation arms and bottom radiation arms, the top radiation arms are arranged at the tops of the radiation arms, and the bottom radiation arms are arranged at the bottoms of the radiation arms; one ends of the top radiation arms and the one ends of the bottom radiation arms are located at the center of the radiation fin and are connected at the center; from the view of vertical projection, the bottom radiation arms are located between adjacent two top radiation arms; and the number of the top radiation arms are the same as the number of the bottom radiation arms, the number of the top radiation arms and the number of the bottom radiation arms both have at least four, both have even numbers and are opposite two by two. The vertical polarized omnidirectional antenna realizes miniaturization and low profile.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a vertically polarized omnidirectional antenna. Background technique [0002] Antenna is the electrical connection bridge in the air in the mobile communication system, and it is one of the most critical components in the entire radio frequency transceiver system. The quality of the antenna directly affects the communication quality. With the development of communication capacity and integrated circuits, antennas are becoming more and more miniaturized, but at the same time, higher quality requirements are put forward for antennas than before. [0003] On the other hand, due to the characteristics of radio waves, it is determined that the horizontally polarized signal will generate a polarization current on the surface of the earth when it is close to the ground. The polarization current will generate heat energy due to the influence of the ground impedance, which will caus...

AI Technical Summary

Problems solved by technology

Affects the appearance, is not easy to bury, has great requirements on the installation conditions, and is not conducive to the miniaturization of the antenna

[0006] Therefore, the main disadvantages of existing vertically polarized omnidirectional antennas are: difficulty in miniaturization, high overall profile
