The embodiment of the invention provides an integrated modulable metamaterial antenna housing and an antenna, as shown in fig. 1, the antenna housing comprises a high-gain antenna and a metamaterial antenna housing, the metamaterial antenna housing is formed by overlapping and fixing three layers of array metamaterial plates, as shown in fig. 2, each array metamaterial plate is formed by N2The metamaterial unit is an N × N array metamaterial plate formed by uniformly arranging metamaterial units on a dielectric plate from top to bottom and from left to right, as shown in FIG. 3, specifically, the array metamaterial plate of the embodiment of the invention can be a PCB printed with the metamaterial units, and through verification, the 7 × 7 array metamaterial plate is the minimum size capable of realizing functions, so that N is more than or equal to 7 in the embodiment of the invention, a high-gain antenna corresponding to the metamaterial unit is an optimized 10GHz microstrip patch antenna serving as a radiation source, the structural design of the metamaterial unit determines the working frequency of the whole design, namely, the frequency band (10 GHz) for realizing high transmission performance, the structure of the metamaterial unit of the embodiment of the invention is shown in FIG. 4, the I-shaped metal structure formed by metal wires and bent inwards at two ends is provided with the length and the width of 5mm, the bending length is too small, the bending length is 1.85mm, the spacing of the metamaterial unit determines the transmission performance, the spacing of the metamaterial unit is too large, the spacing of the metamaterial unit reduces the isolation of the metamaterial to the non-working frequency band, the spacing of the metamaterial unit is determined by the spacing of the antenna, the antenna is determined by the spacing of the antenna from the antenna, the spacing of the antenna is 0.2 mm, the antenna, the spacing of the antenna, the antenna is determined by the antenna, the antenna2And the modulation of the metamaterial unit structure finally realizes the control of the transmission and reflection characteristics of the integrated antenna system on electromagnetic waves with different frequencies.
In order to improve the gain of the microstrip patch antenna, the zero-refractive-index metamaterial plate is used as the antenna cover in the embodiment of the invention, and the zero-refractive-index metamaterial can change obliquely incident waves into plane waves, so that the convergence of antenna radiation beams is realized. 3 layers of the zero-refractive-index metamaterial plate are arranged on the microstrip patch antenna, and researches show that when the metamaterial antenna housing and an antenna radiation source are in close distance and work simultaneously, the strong electromagnetic coupling effect between the two can seriously affect the working frequency, impedance and efficiency of the antenna system, the stability of an antenna system is seriously influenced, through redesign and system optimization, the gap of the metamaterial unit structure is adjusted to be 0.4-0.6 mm, when the distance between a radiation source, namely a microstrip patch antenna and a metamaterial antenna housing, is changed to be 21-25 mm, the metamaterial antenna housing does not influence the performance of the antenna system any more, the integrated design of the antenna and the metamaterial structure of the embodiment of the invention is formed, therefore, regulation and control of far field distribution of the antenna are achieved, the gap position of two adjacent metamaterial unit structures is preferably 0.5mm, and the distance between the microstrip patch antenna and the metamaterial antenna housing is preferably 23 mm.
The metamaterial antenna housing is composed of a multilayer conductive structure, namely an array metamaterial plate, namely a PCB printed with metamaterial units, namely metal wires shown in figure 4, transmission and reflection of electromagnetic waves are controlled by adjusting phase gradients caused by structural parameters and distribution cycles of the metamaterial units, the transmission rate of 10GHz electromagnetic waves is improved, the emission intensity of an antenna is enhanced, the reflectivity is reduced, and the overall efficiency of an antenna system is improved.
The high-gain antenna comprises a dielectric substrate, a high-gain directional radiator, namely a metal microstrip patch antenna, is formed on the dielectric substrate to transmit and receive radio frequency signals, namely RF signals, the high-gain antenna of the embodiment of the invention can adopt the microstrip patch antenna, as shown in figure 5, the high-gain antenna is a structural schematic diagram of the microstrip patch antenna working at 10GHz, S parameters are shown in figure 6, the far field gain of the microstrip patch antenna is 7.428dBi, the far field distribution is ellipsoidal, the gain is low and is easily influenced by surrounding electromagnetic fields, in order to improve the gain of the microstrip patch antenna and increase the transmission performance and the reflection performance of an antenna system to in-band and out-band electromagnetic waves, a metamaterial antenna housing is added above the microstrip patch antenna, as shown in figure 7, the integrated adjustable metamaterial antenna housing loaded with the metamaterial antenna housing and the far field distribution of the antenna assembly on the working frequency are provided, after the metamaterial antenna housing, the adjustment and control of the far field distribution of the microstrip patch antenna are realized, so that the far field beam of the microstrip patch antenna is more concentrated, and the gain of the microstrip patch antenna is improved from 7.428dBi to 9.572dBi as can be seen from the comparison of figures 9-10.
Fig. 8 shows a comparison of simulation results of S parameters of a conventional microstrip patch antenna and an integrated modulable metamaterial radome and antenna assembly (a microstrip patch antenna after loading a metamaterial radome) according to an embodiment of the present invention, and from fig. 8, compared with the S parameters of the conventional microstrip patch antenna, the metamaterial radome enables the resonant frequency of the antenna to be shifted to some extent, but the working frequency (S11 < -10 dB) of the whole antenna system can completely meet the design requirement, and the working bandwidth is improved. The change of S parameters of the microstrip patch antenna loaded by the metamaterial antenna housing is caused by the fact that the metamaterial antenna housing reflects electromagnetic waves emitted by the microstrip patch antenna for many times, but on the required working frequency band, the metamaterial antenna housing enables the beams emitted by the microstrip patch antenna to be more converged, high-efficiency transmission is obtained, and antenna gain is also improved.
The radiation patterns of the microstrip patch antenna and the integrated modulatable metamaterial antenna housing and antenna assembly are compared, as shown in fig. 9-10, it can be seen that after the metamaterial antenna housing is loaded, a main lobe beam of the microstrip patch antenna shrinks towards the center direction, the gain of the microstrip patch antenna is enhanced, and the radiation capability of the antenna is improved.
In order to further verify the designed integrated modulable metamaterial antenna housing and antenna assembly, the corresponding model is processed. As shown in fig. 12 (a) - (c), fig. 12 (a) is a three-layer zero-refractive-index metamaterial structure, fig. 12 (b) is a 10GHz microstrip patch antenna, fig. 12 (c) is an integrated modulatable metamaterial antenna housing and antenna assembly structure, in order to ensure reliability of far-field data, in a test process, the metamaterial integrated antenna is installed at the same horizontal height and fixed so that a distance condition is met between the metamaterial integrated antenna housing and the antenna assembly, and the integrated modulatable metamaterial antenna housing and the antenna assembly are installed on a rotating support and can rotate by 360 degrees, so that complete far-field test data are obtained, as shown in fig. 11. After testing and data arrangement, the simulation of the S parameters of the integrated modulable metamaterial antenna housing and the antenna assembly is basically consistent with the test result, as shown in fig. 6.
According to the embodiment of the invention, three layers of array metamaterial plates, namely metamaterial antenna housings, are adopted to realize in-band efficient transmission of transmission beams, and out-of-band blocking of interference beams can be realized, so that effective electromagnetic shielding can be formed. The embodiment of the invention designs the corresponding metamaterial for the electromagnetic shielding requirement of the corresponding frequency band, and processes the corresponding object for testing. The design level of the researched Ku waveband high-transmission surface, namely the metamaterial antenna housing, is in the lead of the industry, and the researched Ku waveband high-transmission surface has a lead design theory. The complete regulation and control of the electromagnetic wave transmission wave beam are realized in the 10GHz frequency band, and further the miniaturization of the shielding structure with in-band transmission and out-of-band blocking can be realized. Based on an interlayer coupling mechanism of the metamaterial, the transmission type metamaterial designed by the embodiment of the invention has good in-band transmission and out-of-band blocking at a frequency band of 10GHz, realizes a beam gathering function of the metamaterial radome, effectively reduces an electromagnetic coupling phenomenon between the radome and a radiation source, and improves the stability of the whole system.
