Embodiment Construction

[0034] In order to illustrate the structure, features and functions of the present invention in detail, the following preferred embodiments are given together with the accompanying drawings for detailed description.

[0035] see Figure 1 to Figure 3 , the linearly polarized antenna 10 provided by the first preferred embodiment of the present invention includes: a body 20 , a waveguide 40 and a cover 50 .

[0036] The body 20 can define a head 22 and a body 24; the head 22 has two first annular portions 221 with different diameters, and the number of these first annular portions 221 is only for illustration and not as a limitation essentials. The first annular portions 221 are arranged coaxially with the axial center of the body 20 as the axis, and a first annular groove 222 is formed between the first annular portions 221 . The first annular portions 221 mainly determine antenna gain, directivity, and side wave suppression. The body 24 has two second annular portions 241 w...

Abstract

A linearly polarized antenna comprises a body which can define a head part and a body part. The head part is provided with a plurality of first ring-shaped parts in different diameters, the first ring-shaped parts are distributed in a coaxial manner by taking the axial direction of the body as the axis, and first ring-shaped grooves are formed among the first ring-shaped parts. The body section isprovided with a plurality of second ring-shaped parts in different diameters, the second ring-shaped parts are distributed in a coaxial manner by taking the axial direction of the body as the axis, and second ring-shaped grooves are formed among the second ring-shaped parts. The extension directions of the first ring-shaped parts are opposite to the extension directions of the second ring-shapedparts.

Description

technical field [0001] The present invention is related to satellite receiving equipment, in particular to a linearly polarized antenna, which is mainly used in a low noise block down-converter (LNB) to replace the known sink antenna. Background technique [0002] In recent years, due to the rapid development of wireless communication and multimedia, consumers' demand for multimedia has been continuously increasing. In terms of satellite TV, a single satellite program can no longer meet the needs of the public. The integration of multiple satellite programs is the current trend. The early multi-satellite receiving system used a single receiving dish (dish) for a single low noise block down-converter (hereinafter referred to as LNB); The satellite receiving system has been developed into a single receiving dish paired with multiple LNBs to achieve the purpose of receiving signals from multiple satellites. [0003] However, since the azimuth angles of multiple satellites are ...
