Specific embodiment
To keep the purpose of the present invention, content and advantage clearer, with reference to the accompanying drawings and examples, to of the invention
Specific embodiment is described in further detail.
Fig. 1 be the present invention is based on programming realize frequency reconfigurable antenna overall connection schematic diagram, Fig. 2 be the present invention is based on
Programming realizes that the antenna structure layer schematic diagram of frequency reconfigurable antenna, Fig. 3 are that the present invention is based on programmings to realize frequency reconfigurable day
The gating graphic diagram of the antenna of line, Fig. 4 are that the present invention is based on the antenna equivalent model figures that frequency reconfigurable antenna is realized in programming, such as
Shown in Fig. 1 to Fig. 4, the present invention is that one kind can be realized the adjustable antenna of frequency, it include antenna stack, dielectric layer, stratum and
Signal control layer composition.
As shown in Figures 1 to 4, the metal isolated island there are many antenna stacks forms a bidimensional matrix, adjacent metal isolated island
Between use pin connection, the metal isolated island in the middle part of matrix has the pin pipe of four direction up and down, and pin pipe is on state
Similar down and metal realizes the interconnection between metal isolated island；When pin pipe is in off state, it is equivalent to open circuit, realizes metal
Isolation between isolated island；The connection horizontal pin pipe of metal isolated island can be made two bit matrix, matrix unit and practical pin mono-
One is corresponding, and V (1,1) arrives V (1, m) when level is numbered from right to left successively；Numbered vertically is successively H (1,1) to H (1, m+1)；Letter
Number control layer is by the element on or off state of control two matrix units of V, H, all mutual pin conductings in Fig. 1
Metal isolated island forms the structure of Fig. 3, completes the antenna pattern structure of Fig. 3, and equivalent aerial model is as shown in Figure 4.
As shown in figure 4, the analysis method of microstrip antenna can be directly used after changing into classical microstrip antenna theoretical model
It is designed:
According to microstrip antenna theory, Transmission line method is analyzed, resonance frequency:
F=c/ (2*L (e) ^0.5)；
E: the dielectric constant of medium plate；
C: the light velocity；
L: antenna length, unit m；
The basic principle of antenna resonant frequency change is: since the dielectric constant of medium plate is it has been determined that be one normal
Number；The c light velocity is also a constant；The resonance frequency of antenna is inversely proportional with antenna length L, therefore real by the matrix of control pin
The on or off of existing pin pipe realizes that the length variation of length L completes weighing for frequency to realize that resonance frequency changes
Structure function.
As shown in Figure 1, the present invention realizes different figures according to different matrixes, thus realize different resonance frequencies,
Figure is realized different after storage by the element on or off of signal control layer calling two matrix units of V, H
Frequency reconfiguration.
The present invention uses the basic principle of microstrip antenna, and the frequency of antenna and the area of antenna are positively correlated；By changing day
The size of line is to change the reconstruct that the resonance frequency of antenna realizes frequency.The present invention and the prior art contrast, effect
Fruit is actively and it will be evident that the frequency by tuned antenna is adjustable, and the complexity and cost of communication system significantly reduce.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
