Embodiment Construction

[0029] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Preferred embodiments of the application are shown in the accompanying drawings. However, the present application can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the application more thorough and comprehensive.

[0030] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention relates to a dual-polarized yagi antenna. A reflector, an active oscillator and a director are sequentially arranged on an antenna axial rod, the reflector is composed of a long metal piece, the active oscillator is composed of an L-shaped metal piece and is connected with the reflector, the director is composed of a plurality of long metal pieces, and two single-polarization unit antenna structures are orthogonally combined to form the dual-polarization antenna. The antenna is advantaged in that an antenna gain coefficient is effectively improved, polarization loss of signal transmission can be reduced by dual polarization, and signals can be accurately received.

Description

technical field [0001] The invention relates to the field of antenna equipment and technology, in particular to a dual-polarization Yagi antenna. Background technique [0002] Since its invention in the 1920s, Yagi antennas have been widely used in radar, direction finding, and communication fields due to their strong directivity and ease of manufacture, but the disadvantages of narrow bandwidth, low gain, and single polarization have severely limited Development and application of Yagi antenna. Contents of the invention [0003] Based on this, it is necessary to provide a dual-polarization Yagi antenna for the above problems. [0004] A dual-polarization Yagi antenna, including an antenna axial rod, a dual-polarization reflector, a dual-polarization active oscillator, and a dual-polarization director, wherein: [0005] The dual-polarized reflector, the dual-polarized active vibrator and the dual-polarized director are sequentially arranged on the antenna axial rod; the ...
