[detailed description of the invention]
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
For the ease of understanding this utility model, below in conjunction with the accompanying drawings and specific embodiment, this utility model is described in detail.It should be noted that be expressed " being fixed on " another element when element, it can be directly on another element or can there is one or more element placed in the middle therebetween.When an element is expressed " connection " another element, it can be directly to another element or can there is one or more element placed in the middle therebetween.Term " vertical ", " level ", "left", "right" and similar statement that this specification is used are for illustrative purposes only.
As long as just can be mutually combined additionally, technical characteristic involved in each embodiment of this utility model disclosed below does not constitutes conflict each other.
As Figure 1-5, a kind of antenna house, including microlens array 11 and antenna house substrate 12, microlens array 11 is combined by multiple lenticule array elements 111, microlens array 111 is arranged on antenna house substrate 12 surface, and lenticule array element 111 is perpendicular to a magnetic direction of an antenna (not shown).The surface that lens transparency material is made is the optical element of piece, and at the electromagnetic wave of millimeter wave frequency band, quasi-optical technique is used to calculate design, millimeter wave electromagnetic wave can be allowed by forming the effect assembling wave beam after lens, and spherical wave or cylindrical wave that point source or line source send can be transformed into plane wave through lens.Lenticule relative lens also has that volume is little, lightweight, it is integrated to be easy to, the advantage of array, it is possible to eliminate secondary lobe, it is also possible to carry out mathematics weighting for the array element in region, to reach the demand of some direction, angle.For area compared with the big and a fairly large number of antenna array of bay, want the lens using a suitable size bigger to difficulty for reaching reasonable whole structure, and the secondary lobe of bay paper interferes, single lens cannot adapt to the position of each bay, it is impossible to allows each bay be in optimal focal position.In order to solve the problems referred to above, use microlens array, on the basis of classic flat-plate antenna, an independent lenticule array element is configured to each bay, the effect of global focus is reached by design respective lens focal length, by micro lens, the electromagnetic wave incided on diverse location being applied with a bit phase delay, spherical wave or cylindrical wave that point source sends can be transformed into plane wave through lens.This time, radiation just had the directivity specified.The lenticule plane of incidence is a sphere, and the swept area of spherical wave is whole spheroid, is able to concentrate towards a direction by focus energy, and directive gain becomes big.Good directionality, just decreases the energy loss in useless direction, and efficiency is improved.Antenna house substrate plays a fixing effect, microlens array is installed, antenna house substrate should have the characteristic that wave transparent performance is strong, loss of field is little and does not change electromagnetic wave direction, lenticule array element is perpendicular to a magnetic direction of an antenna, the main lobe of antenna is perpendicular to lenticule array element, it is ensured that main lobe radiation direction is in the focus of lens, secondary lobe and back lobe radiation direction not in focus, will not be radiated toward assigned direction by microlens array, radiated is all the useful signal obtained desired by us.
In this utility model embodiment, antenna 13 includes: antenna substrate 1311 and aerial array 131, and aerial array 131 is combined by multiple bays 1311, and aerial array 131 is arranged on antenna substrate 132 surface.The directivity of single antenna array element is limited, for being suitable for the application of various occasions, would operate in two or more individual antenna array elements of same frequency, carry out feed according to certain requirement and spatial arrangements constitutes aerial array, the antenna radiation unit constituting antenna array is referred to as bay.The Main Function of aerial array has: tighten and improve the directivity of radiation field；Add the intensity of high radiation field.
Bay 1311 is used for producing electromagnetic wave, and antenna house is covered on bay 1311 and leaves a segment distance.In this utility model, the electromagnetic wave of indication is radio wave 14, and the lobe that in radio wave 14, radiant intensity is maximum is referred to as main lobe, and the lobe being positioned at main lobe dead astern is referred to as back lobe, and remaining lobe is referred to as secondary lobe or secondary lobe.One of basic function of bay is that the energy obtained from feeder line is radiate to surrounding space, and the two of basic function are towards required direction radiation major part energy." gain " refers to that the radiation pattern intensity in antenna intense radiation direction is taken the logarithm with the intensity ratio of reference antenna.Antenna is passive device, and antenna gain is passive phenomenon, and antenna does not increase excitation, but only redistributes and make to radiate more energy than omnidirectional antenna in some directions.Antenna can not produce energy, and Energy Efficient is simply concentrated to the radiation of certain specific direction or receives electromagnetic wave ability by antenna gain, and antenna gain is the highest, and directivity is the best, and energy is more concentrated, and lobe is the narrowest.
Antenna house and antenna 13 are at a distance of keeping a specific distance.Each lens array element flexibility and changeability, the distributed areas of each lens array element, focal length flexible, the mounting distance scalable of antenna house and antenna has been focused different focal lengths, thus has been weighted signal intensity.
Lenticule array element 111 and the arrangement of bay 1311 one_to_one corresponding.As it is shown in figure 1, lenticule array element and bay one_to_one corresponding, the electromagnetic wave that bay sends sends and focuses on through lenticule array element, and spherical wave or cylindrical wave can be transformed into plane wave in lenticule array element, thus obtain required Waveform.According to aplanatism theory analysis electromagnetic wave transmitting procedure in lenticule array element, be there is by interpolation the antenna house of microlens array, promote antenna radar transmitting-receiving gain and the directivity of wave beam.The bay main lobe radiation being in a position is right against lenticule array element, secondary lobe is less by lenticule transmission, achieve the compacting of secondary lobe, decrease the electromagnetic wave energy loss in useless direction, efficiency is improved, further, secondary lobe and back lobe will not be radiated toward assigned direction by microlens array, and radiated is all our desired useful signal.
