Detailed description of the invention
Below in conjunction with embodiment, this utility model is described in further detail, but embodiment of the present utility model is not limited to this.
As it is shown in figure 1, the present embodiment is a kind of di-lens loads electromagnetic horn, including square-circular waveguide transducer [1], conical horn [2], set the part such as di-lens [3] and the fixing clasp [4] of lens.Square-circular waveguide transducer [1] internal structure is the rectangular aperture form towards round mouth diametric plane gradual change, it is achieved rectangular waveguide TE10 mould is to the transition and conversion of circular waveguide TE11 mould.
Di-lens [3] correction conical horn [2] actinal surface phase contrast, it is achieved electromagnetic horn Internal Spherical Surface wavefront is to the conversion before parallel wave, to improve the antenna pattern of antenna, improves antenna gain.It is shaped as doubled-curved surface profiles, lens material selection dielectric constant is the teflon medium of 2.2, and di-lens surface has ledge structure [5], and the height that each sector protrudes di-lens [3] outer surface is different, the phase contrast of correction exit face, changes the stationary wave characteristic of antenna.Di-lens [3] is fixed on conical horn [2] outfan by the fixing clasp [4] of lens.
Structurally selecting bore diameter is 130mm, is highly 150mm, and input port is the conical-horn antenna of rectangle actinal surface (8.64mm*4.32mm), as it is shown in figure 1, its antenna pattern and port standing wave curve are as shown in Figure 5, Figure 6.To its delivery outlet face portion loaded medium lens on the basis of this cone antenna, lens height is 28.8mm bore diameter is 130mm, as shown in Figure 2, its antenna pattern and port standing wave curve are as shown in Figure 7, Figure 8, can be seen that cone antenna loaded medium lens aft antenna antenna pattern is substantially improved by Comparative result, but its port stationary wave characteristic becomes slightly worse.
The fan-shaped step of 4 highly respectively 0.4mm, 2.4mm, 0.4mm, 2.4mm opened by the antenna implemented according to the present utility model at lens surface, such as Fig. 3, shown in 4, its antenna pattern and port standing wave curve are as shown in Figure 9, Figure 10, can be seen that the antenna implemented according to this invention has good antenna pattern and stationary wave characteristic, physical dimension is greatly shortened, and meets small form factor requirements.
