Triangular spiral slit-hexagonal array composite ultra-wide band antenna and work method thereof

Abstract

The invention relates to a triangular spiral slit-hexagonal array composite ultra-wide band antenna and a work method thereof. The triangular spiral slit-hexagonal array composite ultra-wide band antenna is characterized by comprising a substrate, an antenna ground plate attached to the back side of the substrate, and a triangular spiral slit-hexagonal array composite radiation patch attached to the front side of the substrate; the triangular spiral slit-hexagonal array composite radiation patch is a composite antenna distributed according to a hexagonal array structure; the hexagonal array structure is formed in the mode that six regular hexagons surround one regular hexagon; each regular hexagon area is divided into six equilateral triangles which are filled with small triangular spiralslit antennas, that is, the triangular spiral slit-hexagonal array composite radiation patch comprises 42 small triangular spiral slit antennas. The triangular spiral slit-hexagonal array composite ultra-wide band antenna is simple in structure and reasonable in design, compatibility of mobile communication systems from the second generation to the fifth generation, radio frequency identificationsystems, ultra-wide band communication systems and mobile digital television systems is facilitated, and the radiation performance of each working band is stable and reliable.

Description

Technical field: [0001] The invention relates to a triangular spiral slot-hexagonal array composite ultra-wideband antenna and a working method thereof. Background technique: [0002] At present, after years of development, my country's mobile communication technology has entered the fourth generation of mobile communication, and will soon enter the gate of the fifth generation of mobile communication around 2020, the second generation, third generation, fourth generation, fifth generation Mobile communication wireless signals will coexist in space for a long time. At the same time, radio frequency identification technology, ultra-wideband communication technology, and mobile digital TV technology have also been widely used. Multi-network integration is an important trend in the development of wireless communication technology, which requires a new generation of wireless communication terminals to have multi-band compatibility functions, and can work simultaneously in the ...
