One of very important material in art field.The preparation technology relative maturity of CNT, provided for research CNT antenna
Material conditions.Increasing communication uses higher transmitting and receives frequency now, and especially in the world, communication alliance specifies
After 200GHz frequency range is used for the communication of next step inter-satellite.Actually this wave band has been just in Terahertz (0.1THz-
10THz) in wavelength band.Frequency is higher, it is meant that the electromagnetic wavelength of transmission is shorter.At this time this is special for CNT
Material reformed into research Terahertz antenna ideal material.
Study and pointed out now, as long as incident wavelength and CNT antenna exist into certain corresponding ratio, CNT
Terahertz wave band can radiate and electromagnetic wave absorption.In the present invention.Copper cash is adulterated in CNT, CNT is done all day long
Linear array can further enhance radiation intensity, antenna is obtained higher gain.Therefore, CNT Terahertz antenna is studied
With good Practical significance.
The content of the invention
The present invention is directed to above-mentioned technical Analysis, there is provided a kind of CNT Terahertz antenna, the CNT Terahertz
Antenna is applied to receive and tranmitting frequency is higher than 0.01THz electromagnetic wave, can make corresponding length in nanometer, millimeter even li
The other antenna of meter level.
Technical scheme：
A kind of CNT Terahertz antenna, using CNT nested structure in silicon base, by silicon base, carbon nanometer
Pipe, nested material copper cash and AC power composition, CNT forming array are arranged in silicon base, and the radius of CNT is
0.0001 times of incident wavelength, the gap width between two sections of CNTs are 0.01 times of incident wavelength, and AC power is located at
At gap between two sections of CNTs, and it is connected with the nested material copper cash on both sides, the length of whole antenna is incidence wave ripple
Long 0.5 times.
The CNT-nested material copper wire shaped is linear, I-shaped, Y-shaped or annular.
In the CNT Terahertz antenna model, due to the coupling effect and CNT between CNT and copper cash
Between radiation synergistic effect, improve the radiation gain of antenna.
It is an advantage of the invention that：
In the CNT Terahertz antenna model, due to the coupling effect and CNT between CNT and copper cash
Between radiation synergistic effect, improve the radiation gain of antenna.The CNT Terahertz antenna is due to incident wave frequency rate
Terahertz, the addition of copper cash and array structure, the more common CNT antenna of its gain are significantly increased；With reference to Terahertz
Technology, CNT Terahertz antenna can be applied preferably on the equipment research of such as national defense system.

The design software that this modeling uses is the full wave analysis software CST microwave work based on finite time-domain Integral Technology
Make room, this software can simulate the antenna radiation characteristics of full electromagnetic band, wherein just including THz wave.Circuit model uses
Material is the radio circuit of CNT nesting copper cash.First, in terms of following four-dynamic inductance, electrostatic capacitance, quantum electricity
Appearance, electron spin establish the equivalent circuit of CNT Terahertz antenna.Then the surface electricity of CNT nesting copper cash is obtained
Flow distribution and local Electric Field Distribution.Then Electric Field Distribution is calculated respectively using model, radiant power, intensity, resistance, directionality,
The parameters such as effective area.As a result show, because the plasmon resonant frequency of CNT is in terahertz wave band, so working as antenna
