Embodiment Construction

[0009] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0010] An antenna anti-jamming structure applied to WLAN such as figure 1 As shown, it is composed of a radome 1, a dielectric plate 2, a planar slot antenna 3, a microstrip line 4, two circular conductors 5 and 6, and a feed connector 7. The outer surface of the feed connector 7 is connected to two layers of circular metal conductor plates 5 and 6.

[0011] The feed pin in the center of the feed connector is connected to one end of the microstrip line on the dielectric substrate, and the other end of the microstrip line is connected to the conductor surface where the slot is located, thereby feeding the planar slot antenna on the other surface. The radome mainly protects the internal structure of the antenna.

[0012] Within the working frequency band of WLAN (2400MHz-2483.5MHz) S 11 Below about -15dB, a better impedance matching is achieved and the ene...

Abstract

An interference-resistant structure of a Wlan antenna comprises an antenna cover, a dielectric plate, a planar slot antenna, a feeding microstrip, a metal bottom plate and a feeding connector.

Description

Technical field [0001] The invention relates to an antenna structure. Background technique [0002] Most of the existing WLAN antennas are omnidirectional radiating antennas. When two WLAN omnidirectional radiating antennas are relatively close, mutual interference will seriously affect the user's access rate and data transmission rate. Summary of the invention [0003] The purpose of the present invention is to provide a WLAN antenna that is easy to process, easy to produce, and has anti-interference characteristics against the defects of the prior art. [0004] The technical scheme of the present invention is: an antenna anti-interference structure, which is composed of a radome, a dielectric plate, a planar slot antenna, a feeding microstrip, a metal bottom plate, and a feeding connector. [0005] The feed connector housing is connected with the metal bottom plate and the slot antenna. One end of the microstrip line is connected with the center feed pin of the feed connector, and ...
