Abstract
The invention discloses a broadband electrically small antenna which comprises mutually disjointed long conductor 1 and short conductor 2, wherein the long conductor 1 circles to form a fixed-length helix body; the short conductor 2 is straightened to form a fixed-length straight body; the straight body formed by the short conductor 2 is inserted into the helix body formed by the long conductor 1; the head end of the long conductor 1 is connected to a signal ground end G of a radio-frequency signal; the head end of the short conductor 2 is connected to a signal end S of the radio-frequency signal; the tail ends of the two conductors are suspended; and the inductance coefficient L1 of the long conductor 1 from the head end to the tail end is greater than the inductance coefficient L2 of the short conductor 2 from the head end to the tail end. In the invention, an electromagnetic material is used as a base plate, and the design aims of strong radiating capacity, good ultra-wide band frequency response and small volume are achieved. Through simulation detection, the product has excellent performance, reasonable shape structure and low energy consumption, is environment-friendly and is particularly suitable for large-batch industrial production; and moreover, the production cost is low, and the market prospect is very broad.
Description
Technical field
The invention belongs to wireless communication technology field, be specifically related to a kind of wideband electronically small antenna.
Background technology
The wideband electronically small antenna, as the critical component of mobile communication product, its radiation efficiency, directivity, bandwidth, impedance matching property, size and manufacturing cost have great influence to mobile communication product.And the practical development in current mobile communication market also to the miniaturization of communication products, diversity, light and handy, attractive in appearance increasingly high requirement proposed.But currently marketed wideband electronically small antenna all can not be met the need of market far away from volume, frequency range, radiation efficiency, that aspect of cost.
Summary of the invention
The purpose of this invention is to provide a kind of wideband electronically small antenna, the actual demand that market is little to the electronically small antenna volume to satisfy, bandwidth, radiation efficiency high, cost is low.
The present invention includes mutually disjoint long conductor and short conductors; Wherein, long conductor spirals into the helix body of fixed length, and the straight line body of the stretching one-tenth fixed length of short conductors, the straight line body that short conductors constitutes are inserted in the helix body of long conductor formation; The head end of long conductor is connected to the signal ground end of radiofrequency signal, and the head end of short conductors connects the signal end of radiofrequency signal, and the tail end of two conductors is unsettled; Wherein, the inductance coefficent L of long conductor head end to tail end
1Inductance coefficent L greater than short conductors head end to tail end
2
Described long and short conductor can be arranged on the substrate of dielectric, magnetizing mediums, electromagnetic medium material or in the coating layer.
Radianting capacity of the present invention is strong, ultra wide band frequency responds, volume is little, be particularly suitable for mass industrialized production, low production cost, and market prospects are boundless.

Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are specified:
With reference to accompanying drawing 1, in embodiments of the present invention, comprise mutually disjoint long conductor 1 and short conductors 2; Wherein, long conductor 1 spirals into the helix body of fixed length, the straight line body of short conductors 2 stretching one-tenth fixed length, and the straight line body that short conductors 2 constitutes is inserted in the helix body of long conductor 1 formation; The head end of long conductor 1 is connected to the signal ground end G of radiofrequency signal, and the head end of short conductors 2 connects the signal end S of radiofrequency signal, and the tail end of two conductors is unsettled; Wherein, the inductance coefficent L of long conductor 1 head end to tail end
1Inductance coefficent L greater than short conductors 2 head ends to tail end
2
With reference to accompanying drawing 2,3, can find out that through the 3 dimension antenna patterns and the gain of HFSS system emulation embodiments of the invention have maximum gain in the horizontal direction; Omnidirectional radiation intensity is even, changes less relatively; Maximum gain is near 3dB.
Embodiments of the invention adopt electromagnetic material as substrate, have realized the purpose of design that radianting capacity is strong, ultra wide band frequency responds, volume is little.Product detects through emulation, superior performance, and contour structures is reasonable, and low, the environmental protection of energy consumption is particularly suitable for mass industrialized production, low production cost, market prospects are boundless.
