Abstract

The invention discloses a high-frequency millimeter wave low-profile transmission array antenna, and belongs to the technical field of millimeter wave array antennas. The high-frequency millimeter wave low-profile transmission array antenna comprises a feed source, a PRS array plane located right above the feed source and a transmission array plane located right above the PRS array plane. According to the high-frequency millimeter wave low-profile transmission array antenna provided by the invention, the transmission array plane with a specific structure and arrangement mode is combined with the PRS array plane with a specific structure and arrangement mode, so that the gain fluctuation of the obtained transmission array antenna is less than 3dB and the relative bandwidth is 9.3% within the range of 95.3 GHz to 104.6 GHz; in the 3dB gain bandwidth, the s11 in the range of 95.3 GHz to 95.8 GHz is less than-9dB, and the s11 of other frequency points is less than-10dB; within the range of 95.3 GHz to 104.6 GHz, beam scanning of + / -40 degrees is realized in a two-dimensional space.

Description

technical field [0001] The invention belongs to the technical field of millimeter-wave array antennas, in particular to a broadband low-profile transmission array antenna for high-frequency millimeter-waves. Value. Background technique [0002] As an important working frequency band for future millimeter-wave communications, the high-frequency millimeter-wave frequency band can meet the needs of communication and other electronic devices for wider bandwidth and higher information transmission rates. However, in the high-frequency millimeter-wave frequency band, the large space loss of electromagnetic waves and the approximate linear propagation characteristics make the spatial coverage of the signal a shackle that limits the scale of high-frequency millimeter-wave commercial use. [0003] As a high-gain beam-scanning antenna, the transmissive array antenna integrates space feeding and phase modulation technology. By precisely adjusting the state of each transmission unit, t...
