Embodiment Construction

[0023] The present invention will be further introduced below in conjunction with the accompanying drawings.

[0024] like figure 1 Shown is a schematic diagram of the invention. Including 3 radiators, feed network 2 and base 3. Among them, for the three radiators, in order to reduce the size of the antenna, the high dielectric constant plate TAP-2 is selected as the antenna substrate, and the dielectric constant is equal to 16. The radiation piece 11 works in the S frequency band; the radiation piece 12 works in the L1 frequency band; and the radiation piece 13 works in the L2 frequency band.

[0025] The three radiators are stacked up and down, and the feed network 2 is bonded to the bottom radiator 13 as a whole, and is mounted on the base 3 through lamination screws. A metal post 31 is installed in the center of the base 3, and the metal post 31 runs through the three radiating sheets, realizing the grounding treatment of the three radiating sheets, and reducing the mut...

Abstract

The invention discloses a miniaturized three-band satellite communication antenna comprising three radiation sheets (11, 12 and 13) respectively working in three bands, a feed network (2) and a base (3), wherein the three radiation sheets are stacked and fixed on the base (3) through a lamination screw; and the feed network (2) is connected with the radiation sheet stacked at the bottommost layer into a whole and used for respectively feeding the three radiation sheets. By using the miniaturized three-band satellite communication antenna, the design and installation problems of an antenna in a miniaturized terminal are solved.

Description

technical field [0001] The invention relates to a miniaturized three-frequency satellite communication antenna. Background technique [0002] The multi-frequency antenna is required to realize the multi-frequency operation of the antenna within a limited aperture. The multi-band antenna effectively improves the aperture efficiency of the antenna, realizes the multiplexing of the same aperture of the antenna, and has been widely used in satellite communication, navigation, and data transmission. [0003] In the field of satellite communication, with the development of antenna pan-star technology, the antenna is required to work in dual-frequency or multiple frequency bands. At the same time, within a limited aperture, there are usually strict requirements on the size and weight of the antenna. The microstrip antenna has the advantages of low profile, small weight, and good conformality, and can realize triple-band and multi-band operation through reasonable structural design...
