Embodiment Construction

[0034] In order to make those skilled in the art better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Also see figure 1 FIG. 3 shows a preferred embodiment of the dual-frequency parabolic antenna (hereinafter referred to as the antenna) of the present invention. The antenna is to overcome the insufficiency of the prior art products, and can solve the problem that the 2.4GHz and 5.8GHz frequency bands share a pair of antennas in a simpler and lower cost method.

[0036] like figure 1 As shown, the antenna is divided into three parts in appearance, namely: the clip code component 1, the reflection net 2 and the feed component S. The core part is the feed component S, which will be described separately below.

[0037] like figure 2 As shown, the bottom of the feed is a fixing piece 9, one side of the fixing piece 9 is co...

Abstract

The invention relates to the technical field of antennae and particularly discloses a double-frequency paraboloid antenna. The double-frequency paraboloid antenna comprises a paraboloid reflecting net (2) and a feed source assembly, wherein the feed source assembly comprises a bottom fixing component (9), one side of the fixing component (9) is connected with a fixing pipe (8), and the other side of the fixing component (9) is connected with an antenna connector (10); the top end of the fixing pipe (8) is provided with a double-frequency half-wave vibrator (6), and a first reflector (4) and a second reflector (5) arranged on the upper part of the double-frequency half-wave vibrator (6) serve as feed source radiators.

Description

technical field [0001] The invention relates to the field of antenna technology, in particular to a dual-band directional dual-band parabolic 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 wireless access to the Internet, namely: Wi-Fi (Wireless Fidelity, wireless fidelity) and Wi-max (Worldwide Interoperability for Microwave Access, global 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). The parabolic antennas used in these two frequency bands are mainly single-band, and there are many varieties. From production to storage, sales bring a lot of inconvenience. It is necessary to develop a dual-band parabolic antenna. SUMMARY OF THE INVENTION [0003] In order...
