The ultra wideband antenna can completely cover 3.1-10.6GHz, has the advantages of simplicity in structure, small size, 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 ultra-wideband antenna based on double-T 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 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 stairstepping, arc, 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 the patent No. is CN104022359A, radiation patch is formed by two ellipses of size and a circular combination, design complexity, processing difficulties.Therefore, the ultra-wideband antenna designing a simplification and miniaturization has great importance.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, low-profile, ultra-wideband antenna, particularly a kind of ultra-wideband antenna based on double-T groove that cost of manufacture is low.
The technical solution adopted in the present invention:
A kind of ultra-wideband antenna based on double-T groove, it is characterized in that: include grounding plate (1), medium substrate (2), 50 Ω microstrip feed lines (3), impedance transformer (4), radiation patch (5) and two T-slots (61,62).
Described a kind of ultra-wideband antenna based on double-T groove, it is characterized in that: 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 double-T 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 ultra-wideband antenna based on double-T groove, is characterized in that: radiation patch (5) is rectangle, and is carved with two T-slots (61,62).
Present invention have an advantage that
(1) each several part in the present invention is Common Shape, does not include the labyrinth such as arc, stairstepping, and design is simple, it is easy to processing.
(2) present invention adopts the method spread bandwidth of cutting in radiation patch, it does not have introduces other parasitic element, low-profile, is conducive to the miniaturization of antenna.
(3) medium substrate of the present invention adopts FR4 material, and grounding plate, 50 Ω microstrip feed lines, impedance transformer, radiation patch adopt copper foil material, and both materials market is common, cheap so that the cost of manufacture of antenna is low.

Fig. 2 is the side view of the present invention；
Fig. 3 is the S of the present invention11Characteristic is bent；
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred version of the present invention is described further.
A kind of ultra-wideband antenna based on double-T groove, medium substrate (2) selects FR4 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 2mm；Impedance transformer (4) is for trapezoidal, and height is 2.2mm；Radiation patch (5) is rectangle, and long is 8.6mm for 10mm, width.
Being carved with two T-slots (61,62) in radiation patch (5), two T-slots (61,62) equivalently-sized, horizontal component length is 2mm, wide for 0.3mm, and vertical component length is 2mm, wide for 0.5mm.Cutting can be played and regulates impedance matching and expand the effect of bandwidth.
Grounding plate (1) is positioned at the lower surface of medium substrate (2), and long is 4mm for 18.75mm, width.
From figure 3, it can be seen that a kind of ultra-wideband antenna based on double-T groove that the present invention relates to, bandwidth of operation completely covers 3.1-10.6GHz, and has good matching effect.
