Abstract

The invention provides a three-dimensional antenna manufacturing method based on a shape memory polymer and a three-dimensional antenna. The three-dimensional antenna comprises a functional layer anda shape memory polymer layer. The functional layer has a three-dimensional structure when the three-dimensional antenna is in a use state. The manufacturing method comprises the following steps: providing a shape memory polymer layer with a three-dimensional shaped initial shape; converting the shape memory polymer layer having the shaped initial shape into a shape memory polymer layer having a two-dimensional temporary shape; combining the functional layer with the two-dimensional structure with the shape memory polymer layer with the temporary shape; and changing the shape memory polymer layer combined with the functional layer with the two-dimensional structure to have a shaped initial shape, and driving the functional layer with the two-dimensional structure to deform to form a three-dimensional structure. The method intelligently, simply and conveniently realizes manufacturing of the three-dimensional antenna, and is relatively low in cost, relatively wide in application range andsuitable for manufacturing of the flexible antenna.

Description

technical field [0001] The present invention relates to antennas, and in particular to a method for preparing three-dimensional antennas through shape memory polymers. Background technique [0002] From ancient times to the present, the transmission of information has played a very important role in human life. From the ancient "flying pigeons to send books" to modern voice calls and video chats, communication technology has made great progress and greatly improved people's lives. Generally speaking, there are two main methods of modern communication technology, namely wired transmission and wireless transmission. Compared with wired transmission, wireless transmission equipment is easy to install, has high flexibility, and is not restricted by terrain and environment. It has the advantages of free space, simple portability, etc., so it occupies an important position in the field of modern communication. As an important transmitting device and receiving device in a wireles...
