Problems solved by technology
When the corresponding satellite signal has a dual frequency signal, it cannot be received at the same time
In addition, under this design, due to the limited space between the Ka-frequency waveguides 10 on both sides, only a single Ku-frequency waveguide 20 can be accommodated.
And because the space between the Ka-frequency waveguides 10 on both sides is fixed, it is impossible to add the dual-frequency wave collecting device 5 shown in FIG. 1a between them.

Embodiment Construction
[0034] The invention provides a composite multi-frequency antenna. In a preferred embodiment, the composite multi-frequency antenna of the present invention is a satellite signal receiving device for receiving satellite signals. Especially for the situation that there are multiple satellites of the same frequency or different frequencies within the same angle or close to the angle range, the composite multi-frequency antenna provided by the present invention can exert a good signal receiving effect.
[0035] Such as figure 2 As shown, the composite multi-frequency antenna includes a plurality of first frequency collectors 100 and a second frequency collector 200 . The first-frequency wave collector 100 has a first-frequency waveguide 110 . In this embodiment, the first frequency waveguide 110 is formed at the center of the first frequency collector 100 . The first-frequency waveguide 110 preferably has a square cross-section, that is, it is formed into a cylindrical space; ...

The invention relates to a combined type multifrequency antenna, in particular provides a combined type multifrequency antenna which comprises a plurality of first frequency wave collecting devices and a second frequency wave collecting device, wherein each first frequency wave collecting device is provided with a first frequency waveguide tube, and the second frequency wave collecting device comprises a first wave collecting unit and a second wave collecting unit; the first wave collecting unit and the second wave collecting unit are respectively arranged at two sides of a straight line formed by arranging the plurality of first frequency wave collecting devices; the first wave collecting unit and the second wave collecting unit respectively comprise second frequency waveguide tubes; thesignal output parts at the back ends of the first wave collecting unit and the second wave collecting unit are coupled mutually; and the signals received by the two wave collecting units are combinedinto a single signal, and the single signal is output outside to form a second frequency signal. By adopting the design, the same antenna can be used for receiving signals sent by a plurality of satellites which have approximate angles and two-frequency signals when the satellite density is high.
Description
technical field [0001] The invention relates to a composite multi-frequency antenna; specifically, the invention relates to a composite multi-frequency antenna for receiving satellite signals. Background technique [0002] Recently, with the advancement of space technology, the application of satellites has brought more and more convenience to human beings. The application of satellites in science and technology has many aspects, such as detection, meteorology, global positioning, etc., especially in the application of signal transmission, the current technology is very mature. All communications, data transmission, and audio-visual broadcasting rely on satellites as the relay medium for signal transmission. However, as the demand for satellite signal transmission applications grows, the number of satellites and applicable frequency bands also need to increase accordingly to achieve a balance between supply and demand. [0003] At present, the commonly used satellite commu...
