Title:
ANTENNA, COMMUNICATION DEVICE AND ELECTROMAGNETIC WAVE RADIATION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/247349
Kind Code:
A1
Abstract:
The present application belongs to the technical field of communications, and discloses an antenna, a communication device and an electromagnetic wave radiation method. The antenna comprises a radiation structure (7) and a feed structure (9). The feed structure (9) is used for feeding the radiation structure (7), such that a shaft portion (71) and rod portions (72) alternately radiate electromagnetic waves. The radiation structure (7) comprises the shaft portion (71) and a plurality of rod portions (72), wherein the shaft portion (71) is connected to the rod portions (72), the plurality of rod portions (72) are sequentially arranged in the length direction of the shaft portion (71), and an electromagnetic wave propagation constant of the radiation structure (7) is greater than an electromagnetic wave propagation constant of a free space; and the shaft portion (71) is used for radiating electromagnetic waves to a plane perpendicular to the shaft portion (71), and the rod portions (72) are used for radiating electromagnetic waves to a plane perpendicular to the rod portions (72). The antenna provided in the present application can radiate electromagnetic waves to different planes, thereby enriching the function of the antenna.
