Abstract

The invention discloses a 5G millimeter-wave phased array antenna, comprising phased array units, each phased array unit comprises an antenna unit and a radio frequency connector c; each antenna unitcomprises a radiation part a and a radiation part b; each antenna unit is of a three-layer plate structure and is internally provided with a bilayer radiation patch; each bilayer radiation patch includes four radiation patches in total, namely each radiation patch layer includes two radiation patches; a comb-shaped radiation gap is formed in each radiation patch; and a feeding mode of each antennaunit is gap coupled feeding, and a way that a T-shaped feeding microstrip line and an H-shaped coupling gap are matched is adopted. The antenna disclosed by the invention has the advantages that eachantenna unit reaches more than 30% relative bandwidth, so that aperture efficiency of the antenna disclosed by the invention is effectively improved; in a working frequency band, transmitting loss ofthe antenna disclosed by the invention is reduced, and antenna efficiency is improved; and radiation efficiency and gain of an antenna array are improved.

Description

technical field [0001] The invention relates to the technical field of design of millimeter-wave large-scale array antennas and antenna units, in particular to a 5G millimeter-wave phased array antenna. Background technique [0002] With the rise of 5G mobile services, 5G networks have extremely high speed, large capacity, and extremely low delay; compared with 4G networks, the transmission rate of 5G networks can be increased by 10 to 100 times, and the peak transmission rate can reach 10Gbit / s , and the end-to-end delay reaches the millisecond level. According to the communication principle, the maximum signal bandwidth of wireless communication is about 5% of the carrier frequency. Therefore, the higher the carrier frequency, the greater the achievable signal bandwidth. Among the millimeter-wave frequency bands, the 28GHz frequency band is the most promising frequency band for 5G, and the available spectrum bandwidth of the 28GHz frequency band can reach 1GHz; in contras...
