DUAL-FREQUENCY ANTENNA, ANTENNA ARRAY, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/092412
Kind Code:
A1
Abstract:
The present disclosure belongs to the technical field of communications. Provided are a dual-frequency antenna, an antenna array, and an electronic device. The dual-frequency antenna in the present disclosure comprises: a dielectric substrate, which is provided with a first surface and a second surface oppositely arranged in the thickness direction thereof; a reference electrode, which is provided on the first surface; and a radiation element, a first feed branch node and a second feed branch node, which are all provided on the second surface, a connection node between the first feed branch node and the radiation element being a first feed point, and a connection node between the second feed branch node and the radiation element being a second feed point. The radiation element is provided with a first recess part and a second recess part, the first recess part having a first length, the second recess part having a second length, and the first length and the second length being not equal. The length values of the first length and the second length, and the positions of the first feed point and the second feed point meet requirements such that the frequencies of microwave signals radiated by the first feed branch node and the second feed branch node by means of the radiation element are different.
