Title:
ANTENNA STRUCTURE AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/045865
Kind Code:
A1
Abstract:
The embodiments of the present application provide an antenna structure and a communication device. The antenna structure comprises: a reflecting plate, a central antenna and a parasitic antenna, wherein the central antenna is arranged on the reflecting plate in a penetrating manner, and one end of the central antenna is used for electrically connecting to a feed point, and the other end of the central antenna is suspended above the reflecting plate; the parasitic antenna is arranged around the central axis of the central antenna, and coupled feeding is realized between the parasitic antenna and the central antenna; and both ends of the parasitic antenna are electrically connected to the reflecting plate, and an annular loop is formed between the parasitic antenna and the reflecting plate. The antenna structure provided in the embodiments of the present application achieves the effect of a reconfigurable antenna beam, thereby avoiding the problem of the radiation efficiency of a system being reduced due to the introduction of an insertion loss to a feed circuit.
