Abstract
The invention relates to a patch antenna which is made of metamaterials with a 0 refractive index. The patch antenna comprises two parallel sheets of metamaterials, a feeder line fixing plate, feed source and a fixing structure, wherein the feeder line fixing plate which is parallel to the two sheets of metamaterials is arranged on one side of the two sheets of metamaterials; one side surface of a feed source fixing plate, which is far away from the metamaterials, is provided with the feed source; and the fixing structure is used for connecting and fixing the two sheets of metamaterials and the feeder line fixing plate. The property that a propagation direction of an electromagnetic wave is perpendicular to a surface of a medium wtih a 0 refractive index when the electromagnetic wave reflects from the medium with a 0 refractive index to an air medium with a 1 refractive index is utilized, so that the patch antenna is good in directivity and accordingly high in gain.
Description
[technical field]
The present invention relates to super Material Field, relate in particular to a kind of super material paster antenna.
[background technology]
Super material is a kind ofly to have take man-made structures as elementary cell and with what ad hoc fashion was carried out spatial arrangement that the nature material is that do not had, the new material specific physical chemical property, its special nature is not the chemical composition by its material itself, but determined by the feature of its man-made structures.By meticulous calculating and design, can manually produce the material of various special dielectric constants and magnetic permeability, such as left-handed materials.Because these materials have some characteristics that the nature natural material is not had, therefore super material has broad application prospects.
The special nature of super material depends on the key physical yardstick of material to a great extent, for example crystal is that arrangement is orderly on atomic scale, Just because of this, crystalline material has the physical features that some unformed shapes do not have, analogy thus, the ordered arrangement on other level may obtain the physical property that material did not have of occurring in nature to a certain degree.
On the other hand, paster antenna is often as a kind of cheap and antenna compact conformation is used on various circuit boards.It is a kind of antenna with the tropism, can be used as the transmitter and receiver in mobile device.
At present, the technical staff has adopted the multiple technologies means to improve the gain of paster antenna.Yet, up to the present, not yet someone to propose to adopt refractive index be the paster antenna that zero super material manufactures and designs high-gain.
[summary of the invention]
Technical problem to be solved by this invention is: the unique physical character of utilizing super material, design a kind of paster antenna, the directivity of the paster antenna that the front-to-back ratio of this paster antenna is traditional is more good, and this makes its gain significantly higher than general paster antenna.
The technical scheme that technical solution problem of the present invention adopts is: a kind of super material paster antenna comprises: the feed line fixed head; Be arranged on the feed line on a side surface of described feed line fixed head; And the lip-deep paster of the opposite side that is arranged on described feed line fixed head; Wherein, described paster antenna also comprise be parallel to each other and be parallel to described feed line fixed head and some refractive indexes of being arranged on described paster one side are zero super material, and connect and the fixed structure of fixing described some super materials and described feed line fixed head.
More specifically, this super material is at least two, is preferably two
More specifically, this super material is tabular.
More specifically, the cross section of this super material is rounded.
More specifically, the cross section ovalize of this super material.
More specifically, the cross section of this super material is square.
More specifically, the cross section of this super material is polygon.
More specifically, the cross section of the super material of this sheet is irregularly shaped.
Beneficial effect of the present invention is: make the direction propagation of electromagnetic wave to fix of sending from feed line, the gain that has effectively improved paster antenna by utilizing super material.

Fig. 2 is the stereogram of the paster antenna shown in Fig. 2.
[embodiment]
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Principle of the present invention is: if the electromagnetic wave of any angle is that 0 material is when shining air dielectric (refractive index is 1) from refractive index, its electromagnetic exit direction will be perpendicular to this material, like this, incide at any angle refractive index and be the electromagnetic wave in 0 super material, its from this super material to shine refractive index be 1 air dielectric the time, its exit direction will be basically perpendicular to this super material.Thereby electromagnetic wave just becomes from the past the mode of dispersing propagation to surrounding the mode that fixing direction is propagated that concentrates on.Take the electromagnetic wave that sends from wave source by super material as example, based on above-mentioned principle, these electromagnetic waves from super material outgoing are vertical or be basically perpendicular to the surface of super material, namely have extraordinary directivity.
Fig. 1 has specifically illustrated the cross-sectional view of a kind of square zero super material paster antenna 10 of refractive index according to an embodiment of the invention.As shown in Figure 1, this paster antenna 10 comprises that two parallel surfaces are plate shaped super material 4, and the refractive index of these two super materials is 0.The feed line fixed head 1 parallel with these two super materials 4 is arranged on a side of these two super materials 4.2 of feed lines are arranged on a side surface that leaves these two super materials 4 of this feed line fixed head 1.This feed line can be coaxial line.And, be provided with paster 3 on a side surface of the close described super material 4 of described feed line fixed head 1.In addition, this paster antenna 10 also comprises for connecting and the fixed structure of fixing above-mentioned two super materials 4 and feed line fixed head 1.
Fig. 2 shows the stereogram of the paster antenna 10 shown in Fig. 1.
In the above-described embodiments, the cross section of this super material 4 is square.Yet, in practice, as required, can the Cross section Design that surpass material 4 is circular, polygon, irregular shape, etc.
In the above-described embodiments, only the present invention has been carried out exemplary description, but those skilled in the art can carry out various modifications to the present invention without departing from the spirit and scope of the present invention after reading present patent application.
