Problems solved by technology

[0003] At present, there have been ultra-wideband omnidirectional antennas applied to ultrashort wave communication, but there is often a situation: if the antenna radiator is too long, the high-frequency horizontal plane gain of the antenna will be very low; if the antenna radiator is too short, it will be As a result, the gain and antenna efficiency in the low frequency band will decrease rapidly
Therefore, the existing ultra-wideband omnidirectional antennas cannot broaden the operating frequency band of the antenna while taking into account the antenna efficiency

Abstract

The embodiment of the invention relates to an antenna device and communication equipment thereof. The antenna device comprises at least one high-frequency radiation array element, a nonmetal first supporting assembly, a low-frequency radiation array element, a first magnetic rod and a signal output element which are arranged from top to bottom; the high-frequency radiation array element comprises a first high-frequency radiation body and a second high-frequency radiation body which are opposite array oscillators; a broadband coaxial impedance converter is arranged in the second high-frequency radiation body; the first high-frequency radiator and the second high-frequency radiator are connected through a non-metal second supporting assembly, and the opposite ends of the first high-frequency radiator and the second high-frequency radiator are circular truncated cone structure radiators with preset conicity; a first radio frequency cable of the high-frequency radiation array element is in feed connection with the low-frequency radiation array element through a first supporting assembly, and the first radio frequency cable and a second radio frequency cable of the low-frequency radiation array element are wound on the surface of a first magnetic rod and then are connected to a signal output element; and the second radio frequency cable is in feed connection with the first radio frequency cable. According to the antenna device, the antenna efficiency is considered while the working frequency band of the antenna is widened.

Description

technical field [0001] The present application relates to the technical field of antenna communication, in particular to an antenna device and communication equipment thereof. Background technique [0002] The transmission and reception of radio waves need to be completed by the antenna. As a key component of the communication front end, the importance of the antenna is self-evident. At present, in order to achieve different business needs in ultrashort wave communication, a radio station often needs to be equipped with multiple antennas. However, the carrying radio is limited by the volume of the carrier, and multiple antennas will interfere with each other, making it impossible to work at the same time, and frequent replacement of antennas is not suitable for actual use scenarios. Therefore, the development of ultra-wideband antenna technology is of great significance to ultra-short wave communication. [0003] At present, there have been ultra-wideband omnidirectional a...
