Title:
LOW-FREQUENCY FILTERING UNIT HAVING HIGH PATTERN CONSISTENCY, AND ANTENNA ARRAY
Document Type and Number:
WIPO Patent Application WO/2023/216455
Kind Code:
A1
Abstract:
The present invention provides a low-frequency filtering unit having high pattern consistency, and its own pattern has high consistency. The problem of pattern distortion caused by coupling between low-frequency units and a high-frequency array when the low-frequency units are arranged in the high-frequency array and the problems of high costs, large processing errors, and poor filtering effects existing in existing filtering structure applications can be solved. The low-frequency filtering unit having high pattern consistency comprises oscillator arms, a balun base, balun feed lines, and balun cavity tubes for the balun feed lines to be arranged; each oscillator arm comprises two radiation arms, one end of one of the two radiation arms and one end of the other radiation arm are perpendicularly connected to each other to form an integrated right-angle L-shaped structure; a balun cavity tube is provided at the joint between the two radiation arms, and notch structures are axially and symmetrically provided on the two radiation arms by using a 45° angle bisector of the right-angle L-shaped structure as a center line; four oscillator arms are provided; the four oscillator arms are symmetrically arranged in pairs around the periphery of the balun base along diagonals to form an integral cross-orthogonal structure; the oscillator arms, the balun cavity tubes, the balun feed lines, and the balun base are all made of metal conductors.
