Problems solved by technology

However, when omnidirectional antennas adopt ultra-wideband technology, they usually have to take into account the resonance lengths of different frequency bands at the same time, making it difficult to reduce the size of the antenna, or even larger; and the technology of electrically small antennas usually narrows the working frequency band of the antenna. Therefore, in At the same time, there is a contradiction in solving the problem of wideband and miniaturization of the omnidirectional antenna
[0004] Monopole antenna is a typical omnidirectional antenna, but its narrow operating frequency band and high antenna size cannot meet the current development needs

Embodiment Construction

[0028] Please refer to figure 1 and figure 2 , a kind of small-sized ultra-broadband omni-directional antenna of the present invention, it comprises radiation floor 4; Insulation medium 5 is housed on radiation floor 4; A feeder 2, and described feeder 2 is the small conical shell of upper bottom surface and lower bottom surface body. The upper end of the feeder 2 extends upwards to form a radiator 1, and the radiator 1 is a small conical shell with a large upper bottom and a lower bottom, and the cone angles of the radiator 1 and the feeder 2 are different. In this embodiment, the cone angle of the radiator 1 is 110°-140°, and the cone angle of the feeder 2 is 80°-110°. The height of the radiator 1 is 1 / 3-2 / 3 of the total height of the radiator 1 and the feeder 2 . The height of the feed body 2 is 2 / 3˜1 / 3 of the total height of the radiator 1 and the feed body 2 . Four short-circuit bodies 3, the short-circuit bodies 3 are metal rods. The two ends of the short-circuit b...

Abstract

A small ultra-wideband omnidirectional antenna comprises one radiation floor, one insulating medium, one feed body shaped in a conical shell, one radiating body shaped in the conical shell, at lease one short circuit body and one feed joint. The insulating medium is installed on the radiation floor. The feed body is installed on the insulating medium. The radiating body extends upwards at the upper end of the feed body to be formed, and a taper angle of the radiating body is larger than that of the feed body. Two ends of each short circuit body are respectively connected with the radiating body and the radiation floor. The feed joint is provided with an inner metal core connected with the feed body. The small ultra-wideband omnidirectional antenna is smaller in size and has an ultra-wideband feature.

Description

technical field [0001] The invention relates to a small ultra-wideband omnidirectional antenna, which is used as a small antenna terminal of a mobile communication device. technical background [0002] Mobile communication is a communication method widely used today, and it plays an important role in both military and civilian fields. At present, with the rapid development of large-scale integrated circuit technology, the integration of electronic equipment is getting higher and higher, and the size is getting smaller and smaller. Wireless communication modules with different functions and frequency bands can be integrated in a small space. Therefore, communication Devices are also developing toward compatibility with multiple frequency bands and miniaturization. At present, commonly used wireless communication frequency bands include: GSM (880-960MHz), DCS (1710-1880MHz, TD-SCDMA (2010-2035MHz), TD-LTE (2.3-2.4GHz), Bluetooth (2.4-2.48GHz), WLAN ( 2.4-2.48GHz, 5.15-5.35GH...
