Description

LTE Omnidirectional Vehicle Antenna

technical field

The utility model relates to the field of wireless communication, which is used for LTE vehicle-mounted equipment, and more specifically relates to an LTE omnidirectional vehicle-mounted antenna.

Background technique

The communication system is a combination of wired and wireless, and the transmission and reception of space wireless signals are realized by antennas, so it can be seen that antennas play a vital role in wireless communication systems.

In densely populated areas such as gymnasiums, gatherings, emergency rescue and disaster relief, etc., the quality of communication cannot be guaranteed due to too many terminals, and even the entire communication system is paralyzed. A feasible method is to deploy emergency communication in such areas. The communication method needs to have the characteristics of easy movement and easy assembly. Its working frequency band often adopts the LTE400MHz frequency band. This working frequency band has low frequency and long wavelength. The pattern of the pattern changes with frequency. Therefore, it is necessary to design an antenna product with excellent performance to meet the needs of LTE emergency communication.

Contents of the invention

The purpose of this utility model is to overcome the above-mentioned shortcoming of background technology, provide a kind of LTE omni-directional car antenna with high gain, simple assembly, high roundness of antenna pattern, high reliability and simple assembly.

The technical scheme of the present invention is: an LTE omnidirectional vehicle-mounted antenna, which includes at least one antenna unit, and the antenna unit includes a radome, a central mounting column, a radiation oscillator, a feeder line, a connector and mounting accessories, and the LTE omnidirectional vehicle-mounted antenna The feed structure of the antenna is a dipole structure fed by the center, which can avoid the interference of the feed to the roundness of the antenna.

The connector described is a quick-plug N-type connector.

The antenna unit also includes a choke device.

There are four antenna units in total, and the four antenna units are fed in parallel.

The beneficial effects of the utility model are: the utility model has the characteristics of high gain, simple assembly, high roundness of the antenna pattern, high reliability and simple assembly, and can be well used as an LTE vehicle-mounted omnidirectional antenna.
