Detailed description of the invention
Meta Materials is to be made up of on base material according to ad hoc fashion periodic arrangement the man-made microstructure with certain pattern form.Pattern form and arrangement mode that man-made microstructure is different make Meta Materials have different dielectric constants and different pcrmeabilities so that Meta Materials has different electromagnetic responses.Wherein, when this man-made microstructure is in resonance band, this man-made microstructure will show the dispersion characteristics of height, and the dispersion characteristics of so-called height refer to the impedance of this man-made microstructure, hold perceptual, equivalent dielectric constant and pcrmeability and violent change can occur along with frequency.
The present invention utilizes the above-mentioned principle of Meta Materials, a kind of antenna of design, it utilizes the highly dispersed characteristic of man-made microstructure to be formed at by micro groove structure on the first sheet metal, and the feeder line coupling of this first sheet metal and radio-frequency antenna makes antenna have abundant radiation characteristic thus eliminates the design of impedance matching network and realize the miniaturization of antenna；Additionally, the most also introduce second sheet metal relative with the first sheet metal, this second sheet metal electrically connects with feeder line and produces capacitive coupling with the first sheet metal and the swept area of feeder line is increased by the second sheet metal, decreases the loss of feeder line；Simultaneously because there is medium in the middle of the first sheet metal and the second sheet metal, the capacitance between two metal sheets is caused to change according to the difference of dielectric material electromagnetic property so that the operating frequency of antenna also produces change.
As it is shown in figure 1, Fig. 1 is the structural representation of inventive antenna.In Fig. 1, antenna includes feeder line the 10, first sheet metal the 20, second sheet metal 30, the medium 1 being filled between the first sheet metal 20 and the second sheet metal 30；Feeder line 10 and this first sheet metal 20 are by capacitive coupling feed-in the first sheet metal 20, and the second sheet metal 30 electrically connects with feeder line 10；It is formed with micro groove structure 201 on first sheet metal 20.First sheet metal 20 and the micro groove structure 201 formed on the first sheet metal 20 make the first sheet metal 20 constitute an effective dielectric constant and according to the electromagnetic material of Lorentz lorentz's material resonances model dispersion thus realize changing the purpose of antenna radiation characteristics.
The micro groove structure 201 of the present invention can be the micro groove structure that a kind of or derivative by the most several structures, the compound or group battle array in the complementary folding line structure shown in the dual openings helical ring structure shown in the opening helical ring structure shown in the complementary helix structure shown in the complementary opening resonance loop structure shown in Fig. 2 a, Fig. 2 b, Fig. 2 c, Fig. 2 d, Fig. 2 e obtains.Derive and be divided into two kinds, one is that geometry derives, another kind is that extension is derivative, and geometry herein is derivative refers to that function is similar, variform structure is derivative, such as, derived to class of a curve structure, triangle class formation and other different polygon class formation by square frame class formation；Extension herein derives i.e. offers new groove to form new micro groove structure on the basis of Fig. 2 a to Fig. 2 e；As a example by the complementary opening resonance loop structure shown in Fig. 2 a, Fig. 3 a is that its geometry derives schematic diagram, and Fig. 3 b is that its geometry derives schematic diagram.Herein compound refers to, the multiple superposition of micro groove structure of Fig. 2 a to Fig. 2 e forms a new micro groove structure, as shown in fig. 4 a, be the complementary opening resonance loop structure shown in three Fig. 2 a compound after structural representation；As shown in Figure 2 b, it is that the complementary opening resonance loop structure shown in two Fig. 2 a show the structural representation after complementary helix structure is combined jointly with Fig. 2 b.Group battle array herein refers to be formed an overall micro groove structure by the micro groove structure shown in multiple Fig. 2 a to Fig. 2 e in same metal on-chip array, as it is shown in figure 5, be the structural representation after multiple complementary opening resonance loop structure group battle array as shown in Figure 2 a.As a example by the opening helical ring structure shown in Fig. 2 c, the most all illustrate the present invention.
The manufacturing process forming micro groove structure 201 on the first sheet metal 20 has multiple, such as etch, bore quarter, photoetching, electronics are carved, ion quarter etc., wherein etching is preferably manufacturing process, its step is after designing the topological pattern of suitable micro groove structure, pass through etching machines, utilizing solvent and the chemical reaction of metal to get rid of the metal part of default micro groove structure pattern on the first sheet metal, this first sheet metal i.e. defines described Meta Materials.The material of above-mentioned first sheet metal can be any metal such as copper, silver.
Please continue to refer to Fig. 1.Although the setting of the micro groove structure 201 formed on the first sheet metal 20 and this first sheet metal 20 has solved the problems such as impedance matching of the prior art is complicated, impedance loss is big, antenna size is limited, but when antenna needs to be operated in low frequency, the wavelength that the electromagnetic wave of low-frequency range is corresponding is longer, according to antenna design principles, the electric radiation length of feeder will increase.But the setting of the first sheet metal 20 can not effectively solve this problem, conventional solution is to arrange to increase the couple feed of the feeder line 10 micro groove structure 201 to being formed on the first sheet metal 20 around the first sheet metal 20 multi-turn by feeder 10, but this type of arranges and necessarily makes feed line length long, feeder loss increases so that antenna performance declines.
In Fig. 1, have additional the second sheet metal 30 in the medium one side relative with the first sheet metal 20.Feeder line 10 electrically connects with the second sheet metal 30.The mode of electrical connection is by forming plated-through hole 40 on medium, the most also can be electrically connected with the second sheet metal 30 by feeder line 10 by other conventional electric connection mode.
Second sheet metal 30 and the first sheet metal 20 capacitive coupling, to micro groove structure 201 couple feed formed on the first sheet metal 20.Second sheet metal 30 is effectively reduced the demand of the feeder line 10 micro groove structure 201 couple feed to being formed on the first sheet metal 20 to micro groove structure 201 couple feed formed on the first sheet metal 20.Therefore without increasing feeder line 10 length, and the regulation of the second sheet metal 30 area is simple, only need to adjust the second sheet metal 30 area for different working frequency range.And owing to there is medium in the middle of the first sheet metal 20 and the second sheet metal 30, the capacitance between two metal sheets will be caused to change according to the difference of dielectric material electromagnetic property so that the operating frequency of antenna changes the most therewith.
Above in conjunction with accompanying drawing, embodiments of the invention are described; but the invention is not limited in above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematically; rather than it is restrictive; those of ordinary skill in the art is under the enlightenment of the present invention; in the case of without departing from present inventive concept and scope of the claimed protection, it may also be made that a lot of form, within these belong to the protection of the present invention.
