Title:
ANTENNA, SENSING MODULE, SENSOR, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/022224
Kind Code:
A1
Abstract:
The present application provides an antenna, a sensing module, a sensor, and an electronic device. The antenna comprises a floor board, a main radiator, a first parasitic structure, a second parasitic structure, a feed structure, and a feeder line. The feeder line extends in a first direction towards an end of the feed structure, and the first direction is a polarization direction of the antenna. The first parasitic structure, the main radiator, and the second parasitic structure are sequentially arranged in the first direction, the projections of the first parasitic structure, the main radiator, and the second parasitic structure in a second direction are all located in the plane of the floor board, and the second direction is perpendicular to the plane of the floor board. The first parasitic structure comprises a first parasitic patch and a first conductive column, and two ends of the first conductive column are electrically connected to the first parasitic patch and the floor board, respectively. The second parasitic structure comprises a second parasitic patch and a second conductive column, and two ends of the second conductive column are electrically connected to the second parasitic patch and the floor board, respectively. The solution can inhibit surface waves generated by the floor board of the antenna, improves the radiation performance of the antenna, and reduces the size of the antenna.
