Embodiment

[0023] Such as figure 1 As shown, a flexible 5G multi-band antenna based on liquid crystal polymer includes a substrate and an antenna. The substrate is made of liquid crystal polymer material. The antenna includes a main radiation patch 1 and a coplanar waveguide feeding part 2. The main radiation patch The main body of the sheet 1 and the main body of the coplanar waveguide feeding part 2 are arranged in a "pin" shape. The coplanar waveguide feeding part 2 is located at the lower left and lower right of the main radiation patch. The main radiation patch has two branches, One of them is L-shaped, extending from the left to the top by the main radiating patch, and the other is a rectangular radiating patch located in the center of the entire antenna. The coplanar waveguide ground patch at the bottom right has an L-shaped branch, and the main body of the coplanar waveguide ground patch extends from top to left. The substrate is a 32mm*20mm rectangle, and the outer contour of the...

Abstract

The invention relates to a flexible 5G multi-band antenna based on a liquid crystal polymer. The flexible 5G multi-band antenna include a substrate and an antenna. The substrate is a liquid crystal polymer material, the antenna comprises a main radiation patch and coplanar waveguide feeding parts, the main body of the main radiation patch and main bodies of the coplanar waveguide feeding parts arearranged in a way shaped like a Chinese character pin, and the coplanar waveguide feeding parts are positioned on the bottom left and the bottom right of the main radiation patch. The main radiationpatch is composed of two parts: one part is L-shaped and extends upwards from the left of the main body of the main radiation patch, and the other part is a rectangular radiation patch and is locatedin the center of the whole antenna. The bottom right coplanar waveguide feeding part is provided with an L-shaped branch, extending from the top to the left of the main body of the coplanar waveguidefeeding part. Compared with the prior art, the flexible 5G multi-band antenna has the advantages of flexible material, simple structure, good anti-jamming property and the like.

Description

Technical field [0001] The invention relates to a multi-frequency antenna, in particular to a flexible 5G multi-frequency antenna based on liquid crystal polymer. Background technique [0002] With the rapid development of modern wireless technology, the fifth-generation mobile communication technology (5G), which can greatly improve system capacity, spectrum and energy efficiency, has emerged. Wireless connection has put forward higher and higher requirements for multi-band antennas, and modern communication equipment has more stringent requirements for miniaturization. Therefore, the design of miniaturized multi-band antennas has become a new development trend. Planar printed antennas have attracted widespread attention from academia and industry due to their lower cost, lighter weight and better performance. [0003] However, the current 2G, 3G, and 4G systems will not be replaced immediately. Instead, several communication systems will coexist for a long time. This brings new ...
