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-frequency parabolic antenna for Internet wireless access, which can be applied to Wi-Fi802.11a, 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). The parabolic antennas used in these two frequency bands are mainly single-band, and there are many varieties, which bring a lot of inconvenience from production to storage and sales. It is necessary to develop a dual-band parabolic antenna. Contents of the invention [0...
