Embodiment Construction

[0025] see figure 1 , the present invention is a frequency reconfigurable antenna based on DNA simulation, the structure includes a ground plate 4, and also includes a cylindrical dielectric plate 1 fixed on the ground plate 4 and a coaxial shaft wound on a cylindrical dielectric A double-helix metal conduction strip 2 with the same helix angle on the outer surface of the board 1; one of the double-helix metal conduction strips is connected to the ground plate 4, and the other is connected to the feed circuit by means of a through hole on the ground plate 4; A lumped element 3 is arranged between the double helix metal conduction strips. The double helix metal conduction band can be either left helix or right helix; both have the same structure and are coaxially arranged, but the position of the starting end is different. On the normal plane of the 2-axis of the double helix metal conduction band, the double helix metal conduction band The central angle corresponding to the ...

Abstract

The invention discloses a DNA simulation type frequency adjustable reconfigurable antenna which structurally comprises a ground plate, and further comprises a cylindrical dielectric plate fixed on the ground plate, and double helical metal conduction bands which are coaxially wound on the outer surface of the cylindrical dielectric plate at the same helical angle together with the cylindrical dielectric plate, wherein one of the double helical metal conduction bands is connected with the ground plate, and the other is connected with a feed circuit through a through hole on the ground plate; and the lumped element is arranged between the double helical metal conduction bands. According to the invention, the type and position of the lumped element can be changed to realize the high-gain reconfigurable antenna with two characteristics of wideband and work frequency point adjustability.

Description

technical field [0001] The invention relates to an antenna used in the field of radio communication, in particular to a DNA simulation frequency reconfigurable antenna, which can realize wide bandwidth and multiple frequency bands by changing the type and position of lumped elements. Background technique [0002] As a component used to transmit and receive radio waves, the antenna plays a pivotal role in the wireless communication system and is an indispensable part of the wireless communication system. With the rapid development of high-frequency satellite communication systems, radar, wireless communication systems, especially the construction of global 3G and 4G networks, the requirements for antennas are getting higher and higher. On the one hand, the antenna needs to be able to work in multiple frequency bands, has a variety of working modes and has good transmission performance; ) is considered to be one of the best solutions to the above problems. Reconfigurabl...
