The radiation patch (5) is of a trapezoid shape, the bandwidth can be effectively expanded, the impedance converter (4) can be used for adjusting impedance matching, and the U-shaped groove (6) can be used for simultaneously achieving the effects of adjusting the impedance matching and expanding the bandwidth. The novel ultra wideband antenna has the advantages of simplicity in structure, compact appearance, low fabrication cost and the like, and is expected to play an important role in the technical field of the ultra wideband antenna.
Description
Technical field
The present invention relates to ultra-wideband antenna technical field, particularly a kind of Novel Ultra Wideband Antenna based on U-lag.
Background technology
Antenna is part indispensable in wireless communication system, and its effect is to external radiation or receives electromagnetic wave, and ultra-wide band technology is just occupying leading position as a kind of novel short distance high-speed radiocommunication technology.It is that the time domain short pulse signal utilizing nanosecond carries out radio communication, has that transmission speed is fast, security performance good, transmitting power is little and the advantage such as capacity of resisting disturbance is strong.In February, 2002,3.1-10.6GHz is divided into civilian ultra wideband frequency by FCC (FCC).
At present, the method for designing of ultra-wideband antenna mainly has: (1) changes the form of earth plate or radiation patch, and as adopted spiral type, circle etc., but structure is complicated, not easily processes；(2) introduce parasitic element, but due to the addition of new construction, becoming large-sized of antenna can be caused, be unfavorable for the miniaturization of antenna.Such as the ultra-wideband antenna of design in patent document that Authorization Notice No. is CN202633503U, radiation patch is fan-shaped, and earth plate is semicircle, design complexity, processing difficulties.Therefore, the ultra-wideband antenna designing a simplification and miniaturization has great importance.
Summary of the invention

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred version of the present invention is described further.
A kind of Novel Ultra Wideband Antenna based on U-lag, medium substrate (2) selects tetrachloroethylene material, and length is 27mm, width is 18.75mm, height is 1.6mm.
50 Ω microstrip feed lines (3), impedance transformer (4) and radiation patch (5) are positioned at the upper surface of medium substrate (2), and the length of 50 Ω microstrip feed lines (3) is 6.8mm, wide for 1mm；Impedance transformer (4) is for trapezoidal, and height is 2.2mm；Radiation patch (5) is for trapezoidal, and long limit is 16mm, minor face is 8.6mm, high for 10mm.
Being carved with U-lag (6) in radiation patch (5), the horizontal component length of U-lag (6) is 5mm, wide for 0.6mm, and vertical component length is 1.2mm, wide for 0.5mm.
Grounding plate (1) is positioned at the lower surface of medium substrate (2), and long is 4mm for 18.75mm, width.
A kind of Novel Ultra Wideband Antenna based on U-lag that the present invention relates to, trapezoid impedance changer (4) can play the effect of impedance matching, trapezoidal radiation patch (5) can play the effect expanding bandwidth, and U-lag (6) can reach impedance matching simultaneously and expand the effect of bandwidth.From figure 3, it can be seen that this ultra-wideband antenna bandwidth of operation covers 6.1-10.6GHz, meet the designing requirement of ultra-wideband antenna, and there is good impedance matching effect.
