Embodiment Construction

[0021] Such as Figure 1~4 Shown, a kind of I-type-Cantor composite fractal slot ultra-wideband antenna is characterized in that: it comprises three layers of film substrates, the front of the first layer of film substrates is covered with an induction radiation patch, and the front of the second layer of film substrates is pasted Covered with feed radiation patches, the front of the third layer of film substrate is also covered with induction radiation patches, the back of the third layer of film substrate is covered with barium titanate flakes, and the back of barium titanate flakes is covered with permalloy coating. Both the induction radiation patch and the feeding radiation patch are I-shaped-Cantor composite fractal gap structures, and the I-shaped-Cantor composite fractal gap structure is an I-shaped fractal gap structure as a whole, and the inside of the I-shaped fractal gap structure It is a Cantor fractal slot structure; the I-Cantor composite fractal slot ultra-wide...

Abstract

The invention relates to an I-shaped-Cantor composite fractal slotted ultra-wideband antenna and a preparation method thereof. The antenna comprises three layers of film substrates. The front side ofthe first film substrate layer is pasted with an inductive radiation patch; a feed radiation patch is pasted on the front side of the second film substrate layer; and an inductive radiation patch is pasted on the front side of the third film substrate layer and a barium titanate sheet is pasted on the backs side of the third film substrate layer, and a permalloy coating is pasted on the back sideof the barium titanate sheet. The inductive radiation patch and the feed radiation patch have I-shaped-Cantor composite fractal slotted structures; the I-shaped-Cantor composite fractal slotted structures are I-shaped fractal slotted structures in a whole; Cantor fractal slotted structures are arranged inside the I-shaped fractal slotted structures. The antenna working stably and reliably have advantages of large performance redundancy, strong anti-interference ability, high radiation intensity, certain anti-destructive property, and powerful ultra-wide band working capability.

Description

technical field [0001] The invention relates to an I-shaped-Cantor composite fractal slot ultra-wideband antenna and a preparation method thereof. Background technique [0002] The integration of communication systems of different standards, different communication frequency bands, and different terminal equipment to form a multi-network integration communication system has become one of the most important development trends of wireless communication technology in the 21st century. Mobile communication systems, radio frequency identification systems, ultra-wideband communication systems, and mobile digital TV systems are currently widely used and most promising wireless communication application systems. Their working frequency bands are all located in the microwave frequency band, and terminal equipment and communication protocols have relatively large Commonality, if these four systems are integrated and a multi-purpose intelligent terminal in the microwave frequency band ...
