Description of the Invention: [Technical Field of the Invention] The present invention relates to a squashing lie _ is a symmetrical antenna and a ΜΙΜΟ antenna. [Prior Art] In the conventional antenna design, when the antenna is used in a small space, the operating frequency is low, and the multi-mode problem is worked, the performance of the antenna will be much larger than that of the antenna. The reduction in antenna volume will also affect the electrical length of the antenna, and the antenna radiation efficiency and operating frequency will change. The traditional dipole antenna and PIFA antenna are incapable of facing the problems of small size and wide frequency band of the conventional communication terminal, and the design difficulty is extremely difficult to meet the requirements of use. In the low-frequency design, the traditional antenna only uses the external matching line to realize the multi-mode radiation requirement. 'After adding the matching network in the antenna feeder system, the function is low-frequency and multi-mode, but the radiation efficiency will be extremely great. The reduction is due to a very large portion of the energy loss on the matching network. The well-known super-material small antenna integrates a new type of artificial electromagnetic material in the design' so that its radiation has a very rich dispersion characteristic, and can form a variety of radiation modes, thereby eliminating the cumbersome impedance matching network, which is rich in dispersion characteristics. Great convenience for multi-frequency impedance matching. Despite this, the conventional ultra-material small antennas are subject to great constraints in the design process when faced with problems such as small volume, low operating frequency, and wide-band multimode. 201238150 SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to provide an asymmetric antenna and a field, and the performance of the power is still good. In order to solve the above technical problem, a technical solution adopted by the present invention is to provide a symmetrical antenna 'including a first feeder and a first gold, the first feeder

It is asymmetrical. The symmetry is in the groove; the surface structure: the bamboo t-figure-micro-groove structure and the structure of the second micro-groove structure can be -like - or not. And the first microgroove structure touches the groove, and the degree of asymmetry of 200 can be adjusted as needed. This results in a rich, adjustable multimode spectrum. Further, if necessary, the present invention can also be used in the same metal sheet to have more than three types of tactile materials as shown in Fig. 16. Fig. 16 is a schematic view showing the structure of the asymmetric antenna of the first preferred embodiment of the present invention. In the present embodiment, the asymmetric antenna includes the first dielectric substrate 1 () in addition to the above-described feed line and the first metal piece 2. The first surface of the first dielectric substrate 10 is provided with a first metal piece 2 and a feed line 1 disposed around the first metal piece 2, and the first metal piece 2 is also hollowed out with an asymmetric first micro groove structure 100 and a second Microgroove structure·. The first microgroove structure and the second microgroove structure 200 can be a combination of any of the above structures. For example, 17' is a schematic structural view of an asymmetric antenna according to a seventh preferred embodiment of the present invention. In the present embodiment, the asymmetric mystery includes the second dielectric substrate 201238150 20 overlying the first dielectric substrate 1G as compared with the above-described preferred embodiment. r principle of production I know that 'electric length is to describe the frequency of electric skin changes frequently, electrical length = physical length / wavelength. When the antenna operates at a low frequency, the wavelength of the electromagnetic wave is long, and the physical length before the length of the storage is constant is a necessary choice. However, increasing the physical length is bound to be: the miniaturization requirements. According to the present invention, the substrate 2G is covered on the first dielectric substrate 10, and the electromagnetic wave is emitted from the line on the field. After the second dielectric substrate 2g can be emitted or connected, the overall distributed capacitance increases. According to the formula MAWZB can be long ^ there is a bribe low antenna guardian fresh so that the length of the rider does not change without increasing the physical length. And by changing the second material, the distribution capacitance of the (four) days of the hybrid body === without changing the physical length, the === is designed to work on the first dielectric substrate of the present invention in a very small space. The material can be used to make ancient materials. Among them, the second choice of polymer materials: gas = molecular materials, ferroelectric materials, ceramic materials are preferably Teflon, F4B or FR-4.

And the non-touching slave subtraction _ patch 3 in the sixth preferred real antenna of the present invention. Between the first metal piece 2 and the second metal piece 3 = = 201238150 Molecular polymer, ceramic material, etc. In other embodiments, air may also be used. When the medium is air, the feed line 1 and the second metal piece 3 are electrically connected through the wires. When the medium is a high molecular polymer or a ceramic material, the feed line 1 and the second metal piece 3 are electrically connected to each other by forming metalized through holes on the medium. connection. The metallized via hole can be formed at any position of the medium as long as the effect of electrically connecting the feed line and the second metal piece can be achieved. In the present embodiment, the medium is the dielectric substrate 1A, and the second metal piece 3 is made of a polytetrafluoroethylene (FR-4)'. The second metal piece 3 is provided on the first surface of the dielectric substrate 1 which faces the first surface. The first metal piece 3 and the feed line j are electrically connected through the metallized through hole 4.

In the = frequency, the wavelength of the ' _ segment corresponds to a longer wavelength. According to the antenna design, the original Wei shot is a small contact area. «Long, unfavorable to make r夭 green, miniaturized and longer ship makes the ship loss increase. . The principle of solving the problem is: · The second metal piece The first micro-gold ^ lightly feeding the two places. The second metal piece 3 is required for the first micro-groove structure 1 formed on the first and second sub-pieces 2 to have a (10) line 1 pair and a second = slot structure 200. Therefore, when the antenna is in the low frequency &, the feeder 2 is not added to the light-feeding area t of the feeder. The frequency band can be simply adjusted. Figure 19 is the ninth preferred Wei mode asymmetric antenna 12 201238150 Do not think about it. In contrast to the previous embodiment, the second feed line 5 is included in the present embodiment except for the first feeder line.

A first feed line is disposed around the first metal piece 2, and a second feed line 5 is disposed around the second metal #3. The first feeder line i and the second feeder line 5 are electrically connected through the metallized via 6. In Fig. 20, the portion of the first metal piece 2 where the hatching is drawn is the metal portion of the first metal piece 2. The blank portion (the hollow portion) on the first metal piece 2 indicates the first micro groove structure 1 and the second. The microgroove structure is 2〇〇. In addition, the first feed line i is also indicated by a hatching. Similarly, in FIG. 21, the trowel of the second metal piece 3昼 is the metal portion of the second metal piece 3, and the blank portion (the portion of the clock space) of the second metal piece 3 indicates the third micro groove structure 300 and The fourth microgroove structure 400. Further, the first feed line 5 is also indicated by a hatching. Similarly, the third micro-groove structure 3 and the fourth micro-slot structure 400 may be hollowed out on the second metal piece 3 by etching, drilling, photolithography, electron engraving, ion etching, and the like. In the present embodiment, the first microgroove structure 100 and the second microgroove structure 200 on the first surface a of the dielectric substrate 10 are both open spiral ring structures, and the first microgroove structure 100 and the second microgroove structure 2〇 〇 does not communicate, but its size is different 13 201238150 3 asymmetrical structure. Similarly, the second surface b ^ f of the dielectric substrate U) and the fourth micro-slot structure are both open spiral loops resulting in a structure __ such that the antenna has a resonant frequency of two. In addition, in this embodiment, the first metal piece 2 on the surface of the dielectric substrate ι〇2, the first feed line, the first micro-slot structure, the first-micro-slot structure 200 are projected on the second surface b and the second metal respectively. The sheet 3, the second feed line 5, the third microgroove structure 3〇〇 and the fourth microgroove structure 400 are coincident, which has the advantage of simplifying the process.
