Embodiment Construction

[0019] The following describes specific embodiments of the present invention in conjunction with the accompanying drawings.

[0020] Such as Figure 1-Figure 3 As shown, the antenna unit in a SIW antenna array loaded with a butterfly-like left-handed material unit in the present invention includes: a top dielectric board (1), a middle dielectric board (2) and a bottom dielectric board (3) three-layer dielectric board, It is formed by bonding three layers of dielectric boards; the top dielectric board (1) has a metal patch (4) with gaps on it, the middle layer (2) has a U-shaped metal patch (5), and the bottom dielectric board (3) has a Metal ground and a circle of periodic metal vias (6) embedded in the dielectric substrate along the edge; the antenna units are arranged in a linear arrangement. In order to reduce the size of the antenna, two antenna units share a row of metal vias; A partition wall (7) was erected between the antenna units, and the butterfly-like left-hand ma...

Abstract

The invention discloses an SIW antenna array for a loading butterfly-shaped left-handed material unit, which relates to the field of wireless communication. An antenna unit of the SIW antenna array for the loading butterfly-shaped left-handed material unit includes a top layer dielectric plate (1), an intermediate layer dielectric plate (2), and a bottom layer dielectric plate (3), and the three-layer dielectric plates are bonded together to form the antenna unit; a metal paster (4) is disposed on the top layer dielectric plate (1), a U-shaped metal paster (5) is disposed on the intermediate layer (2), and a round of periodicity metal via holes (6) with dielectric substrates are embedded along the edge are disposed on the bottom layer dielectric plate (3); two antenna units are arranged linearly and share a row of metal via holes; and a partition wall (7) is erected between the two antenna units, and left-handed material units (8, 8') are arranged on the partition wall (7) in an arrayof 2*3. The SIW antenna array for the loading butterfly-shaped left-handed material unit provided by the invention enables the coupling degree between the antenna units to be substantially reduced.

Description

technical field [0001] The invention relates to a SIW antenna array loaded with a butterfly-like left-handed material unit, belonging to the field of wireless communication, and relates to a SIW antenna array loaded with a butterfly-like left-handed material unit. Background technique [0002] Left-handed material is one of the most classic metamaterials, which is defined as having both negative permittivity and negative magnetic permeability in certain frequency bands. Composed of artificial unit structures whose periodic size is much smaller than the working wavelength, this type of material can exhibit extraordinary physical properties that natural materials do not have. [0003] With the rapid development of information technology, wireless communication technology is widely used in all aspects of people's life and social development because it is not restricted by the geographical environment and can carry out information transmission and exchange anytime and anywhere. ...
