Embodiment Construction

[0027] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] The present invention utilizes a wide-angle irradiation feed device with a parasitic matching medium to realize a high-performance and low-profile microwave antenna, and the application frequency band of the microwave antenna can cover most of the frequency bands (5GHz to 40GHz) of the current microwave relay, and realizes short perimeter and even The design without surround greatly reduces the use of raw materials and achieves the best balance between cost and performance. In addition, this microwave antenna also has higher gain and lower profile.

[0029] Such as figure 2 and image 3 As shown, the wide-angle illumination feed device 10 with a parasitic matching medium of the present invention includes a waveguide medium 1, a parasitic matching medium 2, a metal reflective surface 3, a reflection matching step 4, a primary refract...

Abstract

The invention relates to a wide-angle irradiation feed source device with parasitic matched media and a microwave antenna. The wide-angle irradiation feed source device with the parasitic matched media comprises components such as guided wave media, the parasitic matched media, metal reflecting surfaces, reflective matching steps and the like. The parasitic matched media are arranged on the lateral surfaces of the guided wave media. The metal reflecting surfaces are formed on the upper surfaces of the guided wave media. The reflective matching steps are positioned at the bottom ends of the metal reflecting surfaces. Primary reflecting regions are positioned between the guided wave media and the parasitic matched media. Secondary reflecting regions are positioned outside the parasitic matched media, and are parallel to the primary reflecting regions. One end of each circular waveguide is inserted between the corresponding guided wave medium and the corresponding parasitic matched medium. The microwave antenna comprises a paraboloid and the wide-angle irradiation feed source device with the parasitic matched media. One end of the wide-angle irradiation feed source device with the parasitic matched media is fixed at the top end of the paraboloid. The feed source device provided by the invention is in fit with the short-focus paraboloid to realize the high-performance and low-profile microwave antenna, and the manufacturing cost is effectively reduced.

Description

【Technical field】 [0001] The invention relates to the field of antennas, in particular to a wide-angle irradiation feed source device with a parasitic matching medium and a microwave antenna. 【Background technique】 [0002] With the continuous development of communication technology, the application of antennas in the field of communication is becoming wider and wider, and there are more and more types of antennas, such as base station antennas for cellular coverage, terminal antennas for various handheld and mobile devices, and Ground station antennas for geostationary satellite communications. Microwave antenna is also a typical application form of antenna. With the continuous wide application of microwave communication transmission system in various fields of national economy and national defense construction such as communication, electric power and transportation, microwave antenna has also made great progress. [0003] However, as the communication network becomes den...
