Title:
FOLDED WAVEGUIDE CAVITY RESONATOR ANTENNA AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/109756
Kind Code:
A1
Abstract:
A folded waveguide cavity resonator antenna and an electronic device. The folded waveguide cavity resonator antenna comprises a foldable waveguide cavity resonator (1) and a feed structure (40). The foldable waveguide cavity resonator comprises a resonant chamber (10), which is enclosed by a metal structure, and a metal partition (20), which is arranged in the resonant chamber, wherein the metal structure has a slit (101) communicating with the resonant chamber; and the metal partition has a first side edge (201) and a second side edge (202), which are adjacent to each other, slot clearances (104) are respectively formed between the first side edge and an inner wall of the resonant chamber and between the second side edge and the inner wall of the resonant chamber, and the side edges of the metal partition, apart from the first side edge and the second side edge, are fitted and connected to the inner wall of the resonant chamber, so as to partition the resonant chamber into a first chamber (102) and a second chamber (103), the first chamber communicating with the second chamber by means of the slot clearances.
