Description
Technical field
The utility model relates to ultra-wideband antenna technical field, particularly a kind of ultra-wideband antenna based on T-slot.
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 notch cuttype, arc, 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 the patent No. is the ultra-wideband antenna designed in the patent document of CN104022359A, radiation patch is formed by size two ellipses and a circular combination, 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 ultra-wideband antenna based on T-slot 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 ultra-wideband antenna based on T-slot, 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 T-slot (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 ultra-wideband antenna based on T-slot, 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 ultra-wideband antenna based on T-slot, is characterized in that: radiation patch (5) is rectangle, and is carved with T-slot (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, notch cuttype, 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 FR4 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.

Embodiment
Below in conjunction with accompanying drawing, preferred version of the present utility model is described further.
Based on a ultra-wideband antenna for T-slot, medium substrate (2) selects FR4 material, long for 27mm, wide be 18.75mm, high be 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), the length of 50 Ω microstrip feed lines (3) be 6.8mm, wide be 2mm; Impedance transformer (4) is for trapezoidal, and height is 2.2mm; Radiation patch (5) is rectangle, long for 10mm, wide be 8.6mm.
Radiation patch (5) is carved with T-slot (6), T-slot (6) can play and regulates impedance matching and expand the effect of bandwidth, its horizontal component long for 3mm, wide be 0.5mm, vertical component is long be 3.5mm, wide be 0.5mm.
Grounding plate (1) is positioned at the lower surface of medium substrate (2), long for 18.75mm, wide be 4mm.
As can be seen from Figure 3, a kind of ultra-wideband antenna based on T-slot that the utility model relates to, bandwidth of operation is 4.5-9.3GHz, and cover the scope of about 5GHz, relative bandwidth reaches 70%, meets ultra-wideband antenna requirement, and has good matching effect.
