Description
Technical Field
The invention belongs to the technical field of microwave communication, and particularly relates to a low-profile wide-beam dielectric resonator antenna.
Background
The wide-beam antenna is an antenna capable of receiving and transmitting signals in a wide range, and is characterized by maintaining stable gain in a large beam range. The method has the characteristics, and can effectively solve the problems of great increase of the communication data rate of the new generation 5G technology and the occurrence of the instant flow avalanche scene. On the other hand, the dielectric antenna has the advantages of low loss, high efficiency, high design freedom and the like because the dielectric material has no conductor loss, so that the wide-beam dielectric resonator antenna realized by combining the wide-beam antenna and the dielectric antenna has a certain research value.
At present, the research and design of antenna linewidth wave beams mainly comprises the following four implementation modes: the first implementation mode is that circular polarized electromagnetic waves with wider beam angle of the antenna can be obtained by using a spiral antenna, but the spiral antenna has a complex structure and needs fine processing; the second method is that the microstrip antenna radiates maximally in the normal direction, electromagnetic waves generate tangential electric fields on the dielectric substrate, and the beam width is expanded by increasing the area of the maximum dielectric substrate, but the method ensures that the plane size of the antenna is larger and does not accord with the development trend of miniaturization of the antenna; the third method utilizes the complementary characteristic of the magnetic electric dipole radiation pattern, so that the beam width of the antenna can be effectively expanded; a fourth approach is to load the shorting probe and introduce an additional vertical current component near the main radiating element, which can produce a more uniform radiation pattern, but with a higher profile for this type of antenna. Part of the existing wide beam medium antennas are to widen the beam width by combining two complementary modes or fusing some higher order modes; another part is to widen the beam width by designing a special metal ground; in addition, some hybrid designs have been reported to achieve broad beam characteristics by introducing radiation patterns of other additional structures. However, most of the wide-beam dielectric antennas reported at present have the problems of high profile, large planar size and complex structure.

Detailed Description
The invention is further explained in the following detailed description with reference to the drawings so that those skilled in the art can more fully understand the invention and can practice it, but the invention is explained below by way of example only and not by way of limitation.
As shown in fig. 1-4, a low-profile wide-beam dielectric resonator antenna comprises a top metal strip structure 1, a top high-dielectric-constant dielectric strip structure 2, an upper low-dielectric-constant substrate layer 3, an intermediate metal layer structure 4, a lower low-dielectric-constant substrate layer 5 and a bottom feeder structure 6, which are sequentially stacked from top to bottom, wherein the top metal strip structure 1 comprises a first top metal strip 11 and a second top metal strip 12; the top-layer high-k dielectric stripe structure 2 comprises a first dielectric stripe 21, a second dielectric stripe 22 and a third dielectric stripe 23 placed side by side; the upper surface of the first dielectric strip 21 is provided with a first top metal strip 11; the second top metal strip 12 is arranged on the upper surface of the third dielectric strip 23; the first dielectric strip 21, the third dielectric strip 23 and the upper low dielectric constant substrate layer 3 are provided with metallized through holes 31; the first top metal strip 11 and the second top metal strip 12 are connected with the middle metal layer structure 4 through the metallized through holes 31 to form a bent vertical electric wall; the middle metal layer structure 4 is etched with a rectangular groove 41; signals are fed through microstrip feed lines corresponding to the bottom feed line structure 6, and are coupled to and radiated from a dielectric strip resonator formed by the top high-permittivity dielectric strip structure 2, the upper low-permittivity substrate layer 3 and the intermediate metal layer structure 4 through rectangular grooves 41.
First medium stripe 21, second medium stripe 22, third mediumThe strips 23 are made of ceramic material, the dielectric constant is 89.5, and the lengths of the first dielectric strip 21 and the third dielectric strip 23 are respectively 0.18λ 0 ～0.22λ 0 The method comprises the steps of carrying out a first treatment on the surface of the The length of the second dielectric strip 22 is 0.35 lambda 0 ～0.39λ 0 The method comprises the steps of carrying out a first treatment on the surface of the The widths of the first dielectric stripe 21, the second dielectric stripe 22 and the third dielectric stripe 23 are all 0.05λ 0 ～0.09λ 0 Between them.

Rectangular groove 41 has a length of 0.08λ 0 ～0.12λ 0 Wide at 0.04 lambda 0 ～0.06λ 0 Between them.
When the antenna works, signals are fed through microstrip feeder lines corresponding to the bottom feeder line structure 6, and the signals are coupled to the top layer high dielectric constant dielectric strip structure 2 through the rectangular grooves 41 to excite TM of the dielectric strip δ1 And (5) molding. The first top metal strip 11 and the second top metal strip 12 respectively arranged on the upper surfaces of the first dielectric strip 21 and the third dielectric strip 23 are connected with the metalized through holes 31 to form a bent vertical electric wall. When two vertical currents are placed at two ends of the E face of the antenna, the currents are opposite, but the two vertical currents are overlapped in the same phase in the horizontal direction due to the fact that the distance is about half a wavelength, so that the beam width of the E face is expanded; meanwhile, the two are counteracted in opposite phases in the vertical direction, so that the influence on the cross polarization inhibition of the antenna is small. However, the vertical electric wall increases the height of the antenna, and the bent vertical electric wall is adopted to solve the problem, so that the integration with a medium is realized, and the effect of low-profile wide beam is achieved.

The design of this example uses a dielectric constant of 89.5 and a loss angle of 0.0006.
The invention utilizes microstrip feeder line to couple and excite TM of dielectric strip through rectangular slot 41 δ1 And a bending type vertical electric wall is introduced at the edges of the dielectric strips at two sides, so that the integration with the dielectric is realized, and the effects of low profile, small plane size, simple structure and beam widening are achieved.
