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 present application relates to an antenna device and its communication equipment. The antenna device includes at least one high-frequency radiation array element, a non-metallic first support component, a low-frequency radiation array element, a first magnetic rod and a top-down arrangement. The signal output element; the high-frequency radiation array element includes a first high-frequency radiator and a second high-frequency radiator that are paired with each other, and a broadband coaxial impedance changer is arranged inside the second high-frequency radiator; the first high-frequency The radiator and the second high-frequency radiator are connected by a non-metallic second support component, and the opposite ends are all conical radiators with a preset taper; the first radio frequency cable of the high-frequency radiation element passes through the first support The component is connected to the low-frequency radiation array element feeder, and after the second radio frequency cable of the low-frequency radiation array element is wound on the surface of the first magnetic rod, the signal output element is connected; the second radio frequency cable is connected to the first radio frequency cable feeder electrical connection. The antenna device realizes taking into account the antenna efficiency while widening the working frequency band of the antenna.

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...
