Cross-Cantor composite fractal slot ultra-wideband antenna and preparation method thereof

Abstract

The invention relates to a cross-Cantor composite fractal slot ultra-wideband antenna and a preparation method thereof. The cross-Cantor composite fractal slot ultra-wideband antenna comprises three film substrate layers, wherein the front surface of the first film substrate layer is covered with an inductive radiation patch; the front surface of the second film substrate layer is covered with a feed radiation patch; the front surface of the third film substrate layer is also covered with an inductive radiation patch; the back surface of the third film substrate layer is covered with a bariumtitanate sheet; the back surface of the barium titanate sheet is covered with a permalloy coating; the inductive radiation patches and the feed radiation patch are all cross-Cantor composite fractal slot structures; the cross-Cantor composite fractal slot structures are cross-shaped fractal slot structures; and a Cantor fractal slot structures are arranged in the cross-shaped fractal slot structures. The ultra-wideband antenna has a small size, a thin thickness, good radiation performance, stable and reliable operation, large performance redundancy, a good anti-interference ability, and an ultra-wideband working capability.

Description

technical field [0001] The invention relates to a cross-Cantor composite fractal slot ultra-wideband antenna and a preparation method thereof. Background technique [0002] Wireless communication technology has developed rapidly in the 21st century, and a variety of wireless communication systems have been widely used in various fields. Mobile communication system, radio frequency identification system, ultra-wideband communication system, and mobile digital TV system are the four most widely used wireless communication systems that are closely related to people's work and life. They all work in the microwave frequency band. End devices have similar requirements and there is great potential for integration. [0003] Multi-network integration and multi-system integration are important trends in the development of wireless communication technology in the 21st century. If the mobile communication system, radio frequency identification system, ultra-wideband communication syst...
