Abstract
The utility model relates to a kind of Novel Ultra Wideband Antenna based on U-lag, comprise grounding plate (1), medium substrate (2), 50 Ω microstrip feed lines (3), impedance transformer (4), radiation patch (5) and U-lag (6), 50 Ω microstrip feed lines (3), impedance transformer (4) and radiation patch (5) are positioned at the upper surface of medium substrate (2), and grounding plate (1) is positioned at the lower surface of medium substrate (2).Radiation patch (5), for trapezoidal, effectively can expand bandwidth, and the effect of impedance transformer (4) regulates impedance matching, and U-lag (6) can reach the effect regulating impedance matching and expand bandwidth simultaneously.This ultra-wideband antenna has the advantages such as structure is simple, low-profile, cost of manufacture are low, is expected to play a significant role in ultra-wideband antenna technical field.
Description
Technical field
The utility model relates to ultra-wideband antenna technical field, particularly a kind of Novel Ultra Wideband Antenna based on U-type groove.
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 as the positive dominate of one novel short distance high-speed radiocommunication technology.It utilizes the time domain short pulse signal of nanosecond to carry out radio communication, has that transmission speed is fast, security performance good, transmitting power is little and the advantage such as antijamming capability 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 contains: (1) changes the form of ground plate or radiation patch, as adopted spiral type, circle etc., but complex structure, not easily process; (2) parasitic element is introduced, but can adding due to new construction, cause the size of antenna to become large, be unfavorable for the miniaturization of antenna.If Authorization Notice No. is the ultra-wideband antenna designed in the patent document of CN202633503U, radiation patch is fan-shaped, and ground plate is semicircle, and design is complicated, processing difficulties.Therefore, the ultra-wideband antenna designing a simplification and miniaturization has great importance.
Utility model content
The purpose of this utility model is to provide the ultra-wideband antenna, particularly a kind of Novel Ultra Wideband Antenna based on U-type groove that a kind of structure is simple, low-profile, cost of manufacture are low.
The technical scheme that the utility model adopts:
A kind of Novel Ultra Wideband Antenna based on U-type groove, it is characterized in that: comprise grounding plate (1), medium substrate (2), 50 Ω microstrip feed lines (3), impedance transformer (4), radiation patch (5) and U-type groove (6), 50 Ω microstrip feed lines (3), impedance transformer (4) and radiation patch (5) are positioned at the upper surface of medium substrate (2), and grounding plate (1) is positioned at the lower surface of medium substrate (2).
Described a kind of Novel Ultra Wideband Antenna based on U-type groove, is characterized in that: impedance transformer (4) is for trapezoidal, and two ends connect 50 Ω microstrip feed lines (3) and radiation patch (5) respectively.
Described a kind of Novel Ultra Wideband Antenna based on U-type groove, is characterized in that: radiation patch (5) for trapezoidal, and is carved with U-type groove (6).
Advantage of the present utility model is:
(1) each several part in the utility model is Common Shape, does not comprise the labyrinth such as arc, spiral type, simplicity of design, is easy to processing.
(2) the utility model adopts the method spread bandwidth of cutting in radiation patch, does not introduce other parasitic elements, low-profile, is conducive to the miniaturization of antenna.
(3) medium substrate of the present utility model adopts tetrachloro-ethylene material, and grounding plate, 50 Ω microstrip feed lines, impedance transformer, radiation patch adopt copper foil material, and this bi-material market is common, cheap, makes the cost of manufacture of antenna low.

50 Ω microstrip feed lines (3), impedance transformer (4) and radiation patch (5) are positioned at the upper surface of medium substrate (2), the length of 50 Ω microstrip feed lines (3) be 6.8mm, wide be 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, height is 10mm.
Radiation patch (5) is carved with U-type groove (6), the horizontal component of U-type groove (6) long for 5mm, wide be 0.6mm, vertical component long for 1.2mm, wide be 0.5mm.
Grounding plate (1) is positioned at the lower surface of medium substrate (2), long for 18.75mm, wide be 4mm.
A kind of Novel Ultra Wideband Antenna based on U-type groove that the utility model relates to, trapezoid impedance converter (4) can play the effect of impedance matching, trapezoidal radiation patch (5) can play the effect of expanding bandwidth, and U-type groove (6) can reach impedance matching simultaneously and expand the effect of bandwidth.As can be seen from Figure 3, this ultra-wideband antenna bandwidth of operation covers 6.1-10.6GHz, meets the designing requirement of ultra-wideband antenna, and has good impedance matching effect.
