Title:
MICROSTRIP ANTENNA AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/274192
Kind Code:
A1
Abstract:
The present application provides a microstrip antenna and an electronic device. The microstrip antenna comprises a radiator as well as a first feed and a second feed which are for feeding radio frequency signals, the radiator being provided with a first feed point and two second feed points. The first feed point is located at a central position of the radiator, and the first feed point is electrically connected to the first feed for feeding the radio frequency signals into the radiator so as to excite the radiator to generate a TM02 mode. The two second feed points deviate from the central position of the radiator and are disposed spaced apart from the first feed point; the second feed is electrically connected to the second feed points by means of an adjusting circuit, and the second feed points are used for feeding the radio frequency signals into the radiator, and the second feed points excite, by means of the adjusting circuit, the radiator to generate a TM10 mode, and thus the radiator has dual microstrip antenna performance. The microstrip antenna provided in the present application solves the technical problem of the SAR value of existing microstrip antennas being high.
