Embodiment Construction

[0021] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] see also Figure 1 ~ Figure 2 , represents a preferred embodiment of the dual-frequency omnidirectional antenna (hereinafter referred to as the antenna) of the present invention. The purpose of the antenna is to overcome the shortcomings of the existing technical products, and solve the problem of a common antenna in the 2.4GHz and 5.8GHz frequency bands with a simpler structure and lower cost. The antenna is divided into two parts: the outer cover 2 and the radiator: the core part is in the radiator, which is divided into four parts: connector (joint) 7, combiner 5, low-frequency radiation unit 4 (2.4GHz), and high-frequency radiation unit 3 (5.8GHz). Part; the outer cover 2 can cover the radiator, which is a non...

Abstract

The invention, which relates to the antenna technology field, more particularly discloses a double frequency omnidirectional antenna. The double frequency omnidirectional antenna comprises a radiating body. And the antenna is characterized in that: a high frequency radiating element (3), a low frequency radiating element (4), a combiner (5) and a connector (7) are distributed coaxially on the radiating body according to a straight line; a coaxial cable is led out from the connector (7) and is connected to a combination terminal of the combiner (5); and two coaxial cables are led out from high frequency and low frequency output terminals of the combiner (5) as well as are respectively connected to the high frequency radiating element (3) and the low frequency radiating element (4). According to the invention, the antenna is in a linear coaxial shape and a high frequency radiating element and a low frequency radiating element are arranged on the antenna, so that the antenna can work at two wave bands of 2.4 GHZ and 5.8 GHZ.

Description

technical field [0001] The invention relates to the field of antenna technology, in particular to a dual-band directional dual-frequency omnidirectional antenna for Internet wireless access, which can be applied to Wi-Fi 802.11a, 802.11b, 802.11g, 802.11n and Wi-max802. 16e and other communication protocols. Background technique [0002] There are mainly two existing technologies for Internet wireless access, namely: Wi-Fi (Wireless Fidelity, wireless fidelity) and Wi-max (Worldwide Interoperability for Microwave Access, global universal microwave communication technology). Its main working frequency bands are concentrated in the 2.4GHz frequency band (2400-2485MHz) and the 5.8GHz frequency band (5151-5850MHz). However, the omnidirectional antennas used in these two frequency bands are mainly single-frequency bands, and there are many varieties of them, which bring a lot of inconvenience from production to storage and sales. Therefore, it is necessary to develop a dual-band...
