Abstract

The embodiment of the invention discloses an antenna. The antenna comprises a first metal electrode, a second metal electrode and a dielectric functional layer. The first metal electrode and the second metal electrode are respectively positioned on two opposite sides of the dielectric functional layer; the first metal electrode comprises a plurality of transmission electrodes; the antenna also comprises a flexible coplanar waveguide and a feed network, and the flexible coplanar waveguide is electrically connected with the feed network. And the flexible coplanar waveguide is used for feeding an electric signal into the feed network. According to the antenna provided by the embodiment of the invention, the effect of reducing the frame size of the antenna can be realized.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular, to an antenna. Background technique [0002] The antenna is an important radio device for transmitting and receiving electromagnetic waves. It can be said that there is no communication device without the antenna. [0003] The phased array antenna is an upgrade to the traditional antenna. It can quickly and flexibly change the antenna beam and pointing shape according to the target, and can send and receive electromagnetic waves in various frequency bands in the entire space, that is, it can search and track multiple targets. , Accurate completion of tasks such as capture and identification. [0004] However, the phased array antenna in the prior art has the problem of a large frame. Contents of the invention [0005] The invention provides an antenna to reduce the frame size of the antenna. [0006] In a first aspect, an embodiment of the p...
