Title:
OPEN STUB RESONATOR, AND METHOD FOR SCREENING FINISHED PCB ANTENNA BOARD
Document Type and Number:
WIPO Patent Application WO/2024/021317
Kind Code:
A1
Abstract:
An open stub resonator and a method for screening a finished PCB antenna board. The open stub resonator comprises a rectangular shielding ring (1), an open stub line (2) in the rectangular shielding ring, and a transverse line (3) perpendicularly connected to the lower end of the open stub line. The rectangular shielding ring comprises two long sides and two short sides, the two long sides being respectively an upper long side (11) and a lower long side (12). The upper end of the open stub line is not connected to the upper long side of the rectangular shielding ring. The transverse line is provided with a first end (31) and a second end (32), the first end being a signal input end, and the second end being a signal output end. The open stub line has a length of l=(2N+1)*λ/4, N∈0,1,2,3..., wherein the wavelength λ is a wavelength corresponding to the working frequency of a resonance point to be measured. The method for screening a finished PCB antenna board by arranging an open stub resonator on the periphery of the finished PCB antenna board compensates for the defects of screening an PCB antenna board simply by measuring an antenna size in the prior art.
