Embodiment Construction

[0027] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0028] Such as figure 1 As shown, this embodiment provides a technical solution: a wide-angle scanning dual-polarized dipole antenna, including a first metal arm 1, an antenna support post 2, a second metal arm 3 and a feed balun 4;

[0029] The first metal arm 1 is located on the top of the antenna, and is used to improve the impedance fluctuation of the antenna when scanning at a large angle;

[0030] The feed balun 4 is located at the bottom of the antenna, and is used to convert the unbalanced feed of the coaxial line input into a balanced feed;

[0031] The antenna support column 2 is located between the fee...

Abstract

The invention discloses a wide-angle scanning dual-polarization dipole antenna, which belongs to the technical field of antennas and includes a first metal arm, an antenna support column, a second metal arm and a feed balun, and the first metal arm is located at the antenna The top of the antenna is used to improve the impedance fluctuation of the antenna when scanning at a large angle. The feed balun is located at the bottom of the antenna and is used to convert the unbalanced feed of the coaxial line input into a balanced feed. The invention greatly improves the impedance matching when the antenna scans at a large angle, and effectively improves the performance of the wide-angle scan of the antenna; at the same time, the antenna has good cross-polarization performance; finally, since both the metal dipole arm and the top metal arm are made of Longitudinal blade-shaped bending structure, its cross-section is extremely small, it is not easy to accumulate snow and rain, which greatly reduces the impact of snow and rain on the performance and life of the antenna, and can be well applied to heavy rainfall and heavy snowfall, etc. inclement weather conditions.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a wide-angle scanning dual-polarization dipole antenna. Background technique [0002] Antenna is one of the most important components of systems such as wireless broadcasting, wireless communication and wireless detection, and its structure and characteristics determine the working performance of the entire system to a large extent. Due to its excellent beam scanning and beam forming capabilities, phased array antennas have become an important development direction of modern antennas. Radar, communication and other systems often require phased array antennas to have characteristics such as wide operating frequency band, large scanning angle, and low return loss; antennas in some special applications often need to have strong environmental adaptability to adapt to harsh environments. working conditions. [0003] Dual-polarized antennas consist of two antennas with mutually orth...
