Title:
ANTENNA AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/005739
Kind Code:
A1
Abstract:
The present application belong to the technical field of communications. Disclosed are an antenna and an electronic device. The antenna comprises a first radiation structure, a second radiation structure and a switch. The first radiation structure comprises an inverted-F structure and a circuit board, wherein the circuit board is electrically connected to the inverted-F structure by means of a radio-frequency signal port. The second radiation structure comprises a dipole, and the second radiation structure is electrically connected to the first radiation structure by means of a first transmission line. The switch is electrically connected to the first transmission line and the first radiation structure, respectively. When the switch is in a first state, the inverted-F structure is used for exciting, by means of a radio-frequency signal that has been transmitted to the inverted-F structure, the circuit board to radiate electromagnetic waves in a first plane. When the switch is in a second state, the first transmission line is used for transmitting the radio-frequency signal in the inverted-F structure to the second radiation structure, so as to excite the dipole to radiate electromagnetic wave in a second plane. The antenna provided in the present application has a relatively high radiation efficiency.
