Embodiment
Now in conjunction with the accompanying drawings, embodiment further describes the present invention:
Fig. 1 is a structure chart of the present invention, and Fig. 2 is the vertical view of Fig. 1, and Fig. 3 is the left side view of Fig. 1.The radiant body medium of antenna is printed on the FR4 medium substrate 1, the medium substrate size: wide 26mm * long 34mm * high 1.5mm, the dielectric constant 4.4 of medium, the height 1.5mm of medium.The entire antenna size is very little, and is close with the monobasic coin-size.The material that the radiation patch 3 of antenna is used is the copper coating, and this copper coating is extremely thin one deck electric conductor, does not have thickness substantially.Radiation patch is semielliptical, and the major axis of the first half is 14mm, and minor axis is 10mm; Mid portion is a rectangle, long for 14mm, wide be 7mm; The latter half is the semicircle that radius equals 7mm.Radiation patch links to each other with the CPW feeder line 6 of long 6.2mm * wide 2mm, makes antenna have the bandwidth of broad.The CPW feeder line that the symmetrical floor 2 of long 11.6mm * wide 5.5mm and CPW feeder line and medium substrate constitute carries out feed to the radiant body of antenna, with the bandwidth of operation of this broadening antenna.The size in the slit between floor side and feeder line is 0.4mm, and the distance on aerial radiation paster 3 the latter half semicircles and top, floor is 0.5mm.What the length of little C type groove 4 determined is the position of high frequency notch, the position of big C type groove 5 decision low frequency notches.From 3.5mm, its width is 0.9mm to little C type groove distance of center circle from the central vertical downward bias of entire antenna, and the start point that is symmetrical in central axis is 238.26 degree; From 3.7mm, its width is 0.8mm to C type groove distance of center circle from the central vertical downward bias of entire antenna greatly, and the start point that is symmetrical in central axis is 273.9 degree.The length of as can be seen from the figure big C type groove is longer than the length of little C type groove, and the length of the groove of can reaching a conclusion is long more, and the position of notch just is offset to the low frequency place.Resonance has been introduced in the existence of big C type groove and little C type groove, introduces this two C type groove and can obtain the notch function on the basis that antenna is not slotted, and when having than the wideer bandwidth of general antenna, well avoids the interference of described frequency range to the UWB system.Fig. 4 and the emulation of fluting aft antenna and the contrast of actual measurement reflection coefficient preceding for fluting, as seen from Figure 4 except 3.1-4.4GHz and 5.1-5.9GHz, whole 2.3-20.1GHz place return loss is all less than-10dB, this just shows and completes successfully the notch function, and has the bandwidth of 17.8GHz.Fig. 5 is the contrast preceding and fluting aft antenna standing-wave ratio of slotting, also can see as can be seen except 3.1-4.4GHz and 5.1-5.9GHz, the standing-wave ratio at whole 2.3-20.1GHz place is all less than 2, prove that again notch position and bandwidth are up to standard, successfully got rid of worldwide interoperability for microwave access (WIMAX) (3.3-3.7GHz), (5.15-5.35GHz is 5.725-5.825GHz) to the interference of UWB system for C-band satellite communication system and wireless lan (wlan) narrowband systems.
