1, umbrella shape printed antenna: this form antenna form can realize the bandwidth of about 40%, can be used as the radiating element of phase-array scanning, but cannot meet the bandwidth of frequency multiplication.
2, Vivaldi prints broad-band antenna: this form antenna can realize the bandwidth of several frequency multiplication, antenna thickness is thinner, comparatively be suitable for the phased array antenna system being applied in one dimension beam scanning, but the feeder loss due to dielectric-slab can cause the radiation efficiency of antenna to decline, and there is the parasitic radiation effect of feeder line, in battle array, mutual coupling is comparatively large, and dielectric structure need adopt auxiliary member to be fixed, and under severe operational environment, reliability is poor.
3, closed ridged horn, this form is traditional broad-band antenna form, its feature is that bandwidth of operation is more than several frequency multiplication, directional diagram directionality is better, and polarization purity is relatively high, is widely used in the Calibration System of broadband, because its closed bell-mouthed size is larger, and not being suitable in phased array antenna system, the pattern beamwidth of aerial radiation is narrower, and beam scanning gain scan declines very fast.
Utility model content
The purpose of this utility model is to avoid the weak point in above-mentioned background technology and provides a kind of ridged horn phased array antenna unit structure that loads, feature of the present utility model is that impedance bandwidth is wide, and beamwidth is wide, compact conformation, can realize phased array antenna system broadband, large-angle scanning.
The utility model is achieved in that
A kind of ridged horn phased array antenna unit, comprise ridged horn antenna body, described ridged horn antenna body comprises a pair ridge arm 2, the allotment hole 3 be arranged on ridge arm, back of the body chamber 4 and SMA feed connector 5, ridge arm 2 is enclosed by negative camber 6 and positive camber 9 and forms, it is characterized in that: the loading arm 1 having a bending in the arranged outside of positive camber 9, one end of loading arm 1 connects with the top of ridge arm 2, the other end of loading arm 1 is free end, and loading arm 1 one end connected with ridge arm 2 top is the top of loading arm 1.
Wherein, the angle of the bending place of described loading arm is 90 °.
Wherein, the geometric center position of the base plate in back of the body chamber 4 is fixedly installed a cross allotment block 7.
Background technology of the present utility model compares and has the following advantages:
1, the utility model is provided with and loads ridged horn phased array antenna unit 1 parts, it is made up of loading arm 1, ridge arm 2, allotment hole 3, back of the body chamber 4, SMA feed connector 5, high-quality directional beam can be produced in broadband, and adopting the loading arm effective broadening beamwidth 30% of ridged horn, the standing wave bandwidth being less than 2 reaches 5 frequencys multiplication.
2, entire physical structure of the present utility model is simple, compact, compare with other opening ridged horns and closed ridged horn, the broadening beamwidth of radiation pattern, this for wide bandwidth scanning phased array antenna most important, this antenna unit structure form is comparatively applicable in the phased array antenna system of broadband, large-angle scanning.

Embodiment
See figures.1.and.2, a kind of ridged horn phased array antenna unit, comprise ridged horn antenna body, described ridged horn antenna body comprises a pair ridge arm 2, the allotment hole 3 be arranged on ridge arm, back of the body chamber 4 and SMA feed connector 5, ridge arm 2 is enclosed by negative camber 6 and positive camber 9 and forms, it is characterized in that: the loading arm 1 having a bending in the arranged outside of positive camber 9, one end of loading arm 1 connects with the top of ridge arm 2, the other end of loading arm 1 is free end, and loading arm 1 one end connected with ridge arm 2 top is the top of loading arm 1.The geometric center position of the base plate in back of the body chamber 4 is fixedly installed a cross allotment block 7.
In enforcement, the angle of the bending place of described loading arm is 90 °, or is the unspecified angle between 80 ° to 100 °.
In the utility model, the effect of loading arm 1 and ridge arm 2 is radiation or receives wideband electromagnetic signal, completes electromagnetic signal conversion, embodiment adopts aluminum design, utilize Digit Control Machine Tool processing and fabricating, this structure installment is tiltedly split on 8 back of the body chamber, and this design is globality and the reliability of considering antenna structure; The external form of ridge arm is decided by the ridge curve closed, and this design ensure that the non-frequency sex change of the inside and outside wall CURRENT DISTRIBUTION on ridge arm, ensure that the high-quality of antenna pattern in broadband.Loading arm is positioned at the end of ridge arm, its effect is the length extending ridge arm, reach broadening Antenna Operation bandwidth object, do not take larger physical space simultaneously, and the electric current on the epitaxial structure of bending superposes with ridge arm internal current, can realize the effect of broadening radiation pattern beamwidth; Ridge arm 2 overall dimension is decided by the ridge curve 6 closed, and is fixedly mounted on and tiltedly splits on 8, and is fixed by sunk screw; Back of the body chamber 4 is positioned at the bottom of antenna, its rectangular cavity of appearance structure, tuning for antenna match of fixed cross allotment block 7 bottom chamber, and the effect of back of the body cavity configuration ensures that antenna can realize directed radiation and as the vitals of adjustment antenna match; The outer conductor of coaxial switch 5 is closely electrically connected with back of the body chamber 4, and inner wire and another ridge arm electrical contact, achieve the electric excitation of a pair ridge arm.
Ridge arm configuration is arranged on tiltedly splitting of back of the body chamber 4, the gap of certain size is retained between two ridges, between gap, electromagnetic wave has been encouraged for coaxial feed, the size in gap is the important physical parameter affecting antenna match simultaneously, be provided with cross match block in the bottom in back of the body chamber, the standing wave parameter of height to antenna of match block has optimizing regulation effect, affects the intensity of signal at cavity interior resonance, be filled to air dielectric in cavity, lower loss can be realized like this.
Utility model works principle is as follows: when transmitting a signal, and SMA feed connector 5 connects transmitter and transmits, and has encouraged the electromagnetic wave of concussion between ridge, the electric current of the formation concussion in ridge arm 2 and loading arm 1 on outer arm, and is radiated personal space.The reception of antenna and be emitted as reciprocity process, signal has encouraged induced current on ridge arm, and produces the electromagnetic wave of concussion between ridge arm, and extracts signal by SMA feed connector 5, finally outputs to external receiver by coaxial cable.
