The invention provides an antenna structure.
In order to solve the above problem, the present invention provides an antenna structure, referring to fig. 1 to 4, in an embodiment of the present invention, the antenna structure includes:
the antenna structure includes:
an antenna radiator 100;
a metamaterial structure 200 disposed corresponding to the antenna radiator 100;
a conductor array 300 disposed within the metamaterial structure 200;
and the conductive plane 400 is arranged at the side of the metamaterial structure 200, and the conductive plane 400 is insulated from the conductor array 300.
In this embodiment, the antenna radiator 100 may be made of a metal material such as copper or aluminum. The antenna radiator 100 may have a ring structure or a plate structure, and the outer contour of the antenna radiator 100 may be a circle, a square, or a polygon. Of course, in other embodiments, the shape of the antenna radiator 100 may not be limited, and only a radiator capable of forming radiation and reception of electromagnetic energy is needed. When the antenna structure is in operation, the antenna radiator 100 receives electromagnetic energy, converts the electromagnetic energy into an electromagnetic signal, outputs the electromagnetic signal, and feeds the electromagnetic signal to the radio frequency circuit, so that the radio frequency circuit analyzes the received electromagnetic signal. When transmitting a wireless data signal to the outside through the antenna radiator 100, the radio frequency circuit energy is fed to the antenna radiator 100, and the antenna radiator 100 converts an electrical signal into the wireless data signal, radiating electromagnetic energy to the outside, so that the electrical signal is radiated through the antenna radiator 100. The antenna radiator 100 is a metal area, and is used as a small-sized loop antenna to perform non-tuned radiation, that is, the antenna is not in a tuned state in a corresponding working frequency band, and cannot radiate radio frequency signals into space with high efficiency.
It can be understood that the small-sized antenna radiator 100 cannot generate resonance in the 83MHz frequency band, the working efficiency is low, and by arranging the metamaterial structure 200, the metamaterial structure 200 can realize the effect of an electromagnetic structure, so that the radiation capability of the loop antenna is improved, tuning of the loop antenna is realized (as shown in fig. 5), and the working efficiency of the loop antenna is improved by 10-30 dB. Therein, the metamaterial structure 200 may be designed to have properties not found in natural materials, typically consisting of metals and other non-metallic materials. By designing the shape, geometry, size, direction and arrangement of the metamaterial structure 200, the metamaterial structure 200 can control the characteristics of the electromagnetic waves, such as blocking, absorbing, reinforcing, bending the electromagnetic waves and the like, thereby realizing the characteristics of the metamaterial. In this embodiment, the metamaterial structure 200 may be a metamaterial non-metal dielectric structure, and in a specific embodiment, the metamaterial non-metal dielectric may be implemented by using distilled water, and the metamaterial non-metal dielectric is characterized by having a high dielectric constant of 84 and a low conductivity, and thus, the metamaterial size can be reduced while ensuring a low loss.
The conductor array 300 is disposed in the metamaterial structure 200, the conductor array 300 is disposed with a plurality of pillar-shaped conductors uniformly distributed in the metamaterial medium and perpendicular to the conductive plane 400, the conductor array 300 may be a parallel metal conductor array 300, and may be specifically made of a material with good conductivity, such as copper or other good conductors. The conductor array 300 and the metamaterial structure 200 may constitute a metamaterial resonator and may be automatically detuned during the transmission phase and tuned to a desired frequency. Thus, by arranging the metamaterial resonator composed of the metamaterial structure and the conductor array 300 in the antenna structure, the radiation performance can be enhanced, the antenna structure is miniaturized, and the adjustability of the radiation directivity, the adjustability of the frequency and the like of the antenna are realized.
It should be noted that, although the metamaterial structure 200 may reduce the volume of the antenna structure to a certain extent, the size of the metamaterial structure 200 still needs to be set to be larger, in the antenna structure provided with the metamaterial medium, if a resonance is generated in a 83MHz frequency band, the size of the metamaterial structure 200 still needs to reach 150 × 40mm to be realized, which may still cause inconvenience to the assembly and use of the antenna structure in an electronic device, and particularly in a miniaturized and lightweight electronic device, the antenna structure may have a problem of poor antenna performance due to the volume limitation, resulting in that the electronic device cannot be compatible with a small volume and good antenna performance. Therefore, in this embodiment, the conductive plane 400 is disposed on the side surface of the metamaterial structure 200, and the conductive plane 400 disposed on the side surface of the metamaterial structure 200 utilizes the electromagnetic mirror effect to generate an electromagnetic mirror image for the small-sized pillar-shaped conductor, so that the conductive plane 400 equates the effect of the induced charge and the original electric field (original charge) to the mirror charge and the original electric field (original charge). With such an arrangement, the pillar-shaped conductors with the first preset length in the conductor array 300 can be equivalent to the pillar-shaped conductors with the length being multiple of the length in the conventional design, so that the metamaterial structure 200 greatly reduces the size requirement. The conductive plane 400 may be made of a material with better conductivity, such as copper or other good conductors, and the conductive plane 400 may be distributed on both sides of the metamaterial structure 200, or may be distributed on both sides of the metamaterial structure 200, specifically, the side of the metamaterial structure 200 perpendicular to the pillar-shaped conductors in the conductor array 300.
The antenna structure of the present invention arranges the metamaterial structure 200 at a position corresponding to the antenna radiator 100, and arranges the conductor array 300 in the metamaterial structure 200. The invention is also provided with a conducting plane 400 arranged at the side of the metamaterial structure 200, and the conductor array 300 and the conducting plane 400 are arranged in an insulating way, so that the conducting plane 400 is added at the side of the metamaterial, the design of the metamaterial antenna with small size and high performance is realized through the mirror image effect, and the requirement of reducing the structural size of the metamaterial can be met under the condition of not reducing the performance of the antenna.

The single-sided conductive plane 400 structure can also reduce the size of the metamaterial structure 200, but the effect is half of the double-sided conductive plane 400, and the protection scope is also within the scope. Specifically, by disposing the conductive planes 400 on two opposite sides of the rectangular metamaterial structure 200, that is, by disposing the conductive planes 400 on two opposite side surfaces of the rectangular metamaterial structure 200, the size of the metamaterial structure 200 can be reduced to 1/3 of the original size. By disposing the conductive plane 400 on the side of the rectangular meta-material structure 200 perpendicular to the conductor array 300, that is, by disposing the conductive plane 400 on the side of the rectangular meta-material structure 200, the size of the meta-material structure 200 can be reduced to 1/2.
