Title:
LOW-FREQUENCY OSCILLATOR UNIT, MULTI-BAND ARRAY ANTENNA AND ADJUSTMENT METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/082360
Kind Code:
A1
Abstract:
A low-frequency oscillator unit, a multi-band array antenna and an adjustment method therefor. The low-frequency oscillator unit comprises a first microstrip oscillator arm (1), a second microstrip oscillator arm (2), and a support structure (3). The first microstrip oscillator arm (1) and the second microstrip oscillator arm (2) are both T-shaped thin arm structures having two upward vertical arms, a millimeter-scale thickness, and forming a straight line when viewed from above. The support structure (3) is provided with a clamping groove structure for clamping and supporting the first microstrip oscillator arm (1) and the second microstrip oscillator arm (2). The multi-band array antenna has multiple columns and/or quasi-columns, and at least one column or quasi-column of the multiple columns and/or quasi-columns is composed of the low-frequency oscillator unit as described above. The low-frequency oscillator unit is characterized by weak coupling and low shielding, is flexibly nested, and allows for a large amount of layout freedom. The multi-band array antenna allows for a large amount of layout freedom and beam adjustment freedom.
