Broadband wide-beam dual-port millimeter wave digital coding antenna with bottom feeding

Abstract

The invention provides a broadband wide-beam dual-port millimeter wave digital coding antenna with bottom feeding. The invention comprises an upper-layer radiation patch structure, a lower-layer parasitic patch structure and a dual-radio-frequency connector port, wherein the upper-layer radiation patch structure adopts a discrete gridding binary coding form to realize an irregular patch structure,and reprocessing is carried out at a point-to-point position to form a rectangular strip-shaped surface structure; the lower parasitic patch structure adopts a discrete gridding binary coding form torealize an irregular patch structure, reprocessing is carried out at a point-to-point position to form a rectangular strip-shaped surface structure, and the lower parasitic patch structure is locatedbelow the upper radiation patch structure and is connected with the radiation patch and the floor through two probes; and the dual-radio-frequency connector port is arranged at the bottom of a bottom-fed broadband wide-beam dual-port millimeter wave digital coding antenna. The quasi-coaxial impedance matching port can be directly connected with a millimeter wave radio frequency connector, and isconvenient to connect and use.

Description

technical field [0001] The present invention relates to the field of antennas, in particular to a bottom-fed wide-bandwidth beam dual-port millimeter-wave digital coding antenna, especially a millimeter-wave digital coding antenna array element with wide bandwidth angle dual-port feeding and a large Linear array of angular sweep characteristics. Background technique [0002] Since in practical application, the receiving antenna (transmitting antenna) needs to work in a wider frequency band to receive signals (transmitting signals), it has certain stability in the contemporary electromagnetic environment, and the communication distance should be far enough (the noise figure should be Small), the link quality should be high enough, and the receiving (transmitting) level should be large enough. However, the general antenna frequency band is narrow, the data capacity in the bandwidth is insufficient, and due to the shortage of spectrum resources and the rapid development of mod...

[0003] The patent document "Design and Analysis of a Reflect-array Using Slot AntennaElements for Ka-band SatCom" proposes a dual-port, array element and antenna array. Although the antenna has dual-port radiation and high port isolation, and the array scanning characteristic reaches 60 degrees, but the antenna still does not solve the broadband characteristics, causing inconvenience to users when it has a high channel capacity
