Structure
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings:
As shown in Figures 1 to 4, a kind of monopole antenna based on flexible wearable application, including earth plate 1, medium base
Plate 2, feeding network 3 and radiation patch 4, medium substrate 2 made by FR4 (epoxy resin) panel material commonly used, and relative dielectric is normal
Number is 4.4, and loss tangent value is 0.02, and thickness is 1.6mm, and the shape of antenna is as it is shown in figure 1, antenna uses side feedback mode, defeated
Entering impedance is 50 Ω.
Antenna in the present embodiment is to be produced on, by engraving method, the medium that specification is 35mm × 30mm × 1.6mm
On substrate 2, earth plate 1 etches in medium substrate 2 side, and the opposite side of medium substrate 2 is etched with feeding network 3 and radiation patch
4, feeding network 3 is made up of microstrip line, and earth plate 1 is rectangular configuration wide with medium substrate 2, and width is 30mm, radiation
The top of paster 4 is etched with groove 5, a width of 15mm of the present embodiment further groove 5, the left and right sides of groove 5 one relatively symmetrically
Being provided with convex projection 6 (see Fig. 3), the protruding height of convex projection 6 is 1mm, and the distance between convex projection 6 is 5mm,
The left and right sides of the bottom of radiation patch 4 is provided with trapezium structure 7 relatively symmetrically.
Being illustrated in figure 4 the inventive antenna concrete size after optimizing design, parameter is as follows: L=35mm, L1=
13.5mm, L2=13.5mm, L3=14.5mm, L4=16.5mm, L5=9.5mm, L6=11.5mm, L7=12.5mm, L8=
14.5mm, W=30mm, W1=5mm, W2=9mm, W3=15mm, W4=17mm, W5=13mm, h1=5m, medium substrate 2 is thick
Degree is 1.6mm, and medium substrate 2 is presented herein below the earth plate 1 of rectangle.Fig. 5 is that inventive antenna master in the case of deforming upon regards
Figure.
For the radiation characteristic of researching antenna, use the emulation of all-wave 3 D electromagnetic, antenna is imitated at 4GHz frequency
True optimization, obtains antenna directional diagram at different frequency, and is analyzed simulation result.Fig. 6 is not sending out for antenna
