A 120° Sector Dual Polarization Broadband High Gain Antenna

Abstract

The invention discloses a 120° sector dual-polarization wide-band high-gain antenna, which comprises a dual-polarization microstrip vibrator array, a feeding microstrip circuit board, a reflection base plate, an antenna cover and the like. The dual-polarized microstrip oscillators are arranged in a linear array in a certain order, and are respectively connected to the feeder microstrip circuit board, which is fixed on the reflection base plate, and then inserted into the antenna cover of the present invention. The performance of the antenna of the present invention is very superior: precise coverage of 120° sector (accurate to ±5°), dual polarization (±45°), wide frequency band (such as 4.9~6.4GHz frequency bandwidth 26.5%), high gain (full In-band G≥17dBi), with an electrical downtilt angle of 1-10°; the whole module processing technology has high precision and low cost, which is convenient for mass production and quick installation; the antenna is wind-resistant, anti-corrosion, waterproof, and durable.

Description

technical field [0001] The invention relates to the technical field of mobile communication and wireless transmission, and more specifically relates to a 120° sector dual-polarization broadband high-gain antenna. Background technique [0002] With the advent of the information age, ultra-high-speed, ultra-wideband 5G network technology is changing people's production and lifestyle. Wherever there are traces of human activities, there is a need for fast-transmitting wireless information network guarantees. However, so far, many 120° sector antennas can only cover 100°-108° sector planes, which is far from the precise coverage required for 120°±5°, and there is a lack of dual-polarization, wide-band, high-gain 120 ° sector antenna. The main reason for these problems and defects is still a technical problem. Although this problem has been proposed earlier, it has not been resolved after all. [0003] Therefore, how to provide a 120° sector dual-polarized broadband high-gain a...
