Application principle of the invention is explained in detail with reference to the accompanying drawing.
As shown in Figure 1, anti-transmission integrated multi-functional plane sky feedback array antenna provided in an embodiment of the present invention includes:
Vivaldi antenna, array element, double circular ring shape frequency-selective surfaces；
Vivaldi antenna is as the feed of plane sky feedback array antenna, using the cross-shaped oscillator of four-layer structure as battle array
Column unit, and double circular ring shape frequency-selective surfaces are loaded in unit bottom end；Planar array is by various sizes of cross-shaped oscillator
Made of double circular ring shape frequency-selective surfaces unit periodic arrangements of unit and identical size, each unit on array is pressed
Respective phase is compensated according to the mode for adjusting cross-shaped oscillator size, to guarantee that plane sky presents array after feed irradiates
Antenna can array forward or backward formation with phase high-gain radiation beam.
Application principle of the invention is further described with reference to the accompanying drawing.
Anti- transmission integrated multi-functional plane sky feedback array antenna of the invention includes: Vivaldi antenna as the plane
The feed of sky feedback array antenna loads double circles as array element, and in unit bottom end using the cross-shaped oscillator of four-layer structure
Annular frequency-selective surfaces.Planar array is selected by double circular ring shape frequencies of various sizes of cross-shaped oscillator unit and identical size
Made of selecting surface cell periodic arrangement, each unit on array is in the way of adjusting cross-shaped oscillator size to respective
Phase compensate, thus guarantee after feed irradiates plane sky feedback array antenna can be in the forward or backward formation of array
With phase high-gain radiation beam.The functional schematic of anti-transmission integrated multi-functional plane sky feedback array antenna of the invention is as schemed
Shown in 2:
It can be seen from the figure that anti-transmission integrated multi-functional plane sky feedback array antenna can realize plane in high band
The function of transmiting array antenna, to realization high-gain radiation beam before array；The function of plane reflection array antenna is realized in low-frequency range
Can, to realization high-gain radiation beam after array.Therefore, plane sky of the invention feedback array antenna can be by changing frequency
Realize the flexible modulation of its radiation direction.
Array element structure is as shown in Figure 3: it can be seen from the figure that multifunctional array unit of the invention is using four layers of knot
Structure, the upper surface of every layer of dielectric-slab are covered with metal cross-shaped oscillator, and double circular ring shape frequency-selective surfaces unit loads are at the 4th layer
The bottom end of dielectric-slab.Wherein, metal cross-shaped oscillator is phase modulation unit, can be to unit by way of changing oscillator length L
Electromagnetic scattering phase is adjusted；The effect of double circular ring shape frequency-selective surfaces is that reflection characteristic is presented in low-frequency range, to feedback
The incidence wave that source issues is by unit total reflection (being equivalent to metal floor)；Transmissison characteristic is presented in high band, feed is issued
Incidence wave pass through unit total transmissivity (being equivalent to high-pass filter).Therefore, array element can by switching different frequency and
The mode for changing cross-shaped oscillator size realizes the separately adjustable of anti-transmission phase at different frequency.
Fig. 4 gives pair amplitude of the anti-transmission coefficient of annulus frequency-selective surfaces and phase with the situation of change of frequency.
From Fig. 4 (a) as can be seen that at low-frequency range (8~9.5GHz), the reflection coefficient amplitude of double annulus frequency-selective surfaces is 0.9
More than, most of incident electromagnetic wave is totally reflected；At high band (11~12.5GHz), double annulus frequency-selective surfaces it is saturating
Coefficient amplitude is penetrated 0.9 or more, to most of incident electromagnetic wave total transmissivity.Therefore, using double annulus frequency-selective surfaces in height
(low) frequency shows (anti-) and penetrates characteristic, it is ensured that the transformation of anti-transmissison characteristic is realized by switching frequency.But from Fig. 3
(b) as can be seen that double anti-transmission phase shift variations ranges of the annulus frequency-selective surfaces in 8~12.5GHz is smaller (at 200 degree
Left and right), it cannot be used to adjust anti-transmission phase.
The amplitude and phase that Fig. 5 gives the anti-transmission coefficient of the cross-shaped oscillator unit of four layers of dielectric-slab structure are with frequency
Situation of change.From Fig. 5 (a) as can be seen that transmissison characteristic, transmission coefficient is presented in unit (8.6~12.5GHz) in entire frequency band
Amplitude is maintained at 0.8 or more, so the unit only realizes transmission in entire frequency band, it cannot be guaranteed that passing through switching frequency reality
The now transformation of anti-transmissison characteristic.But it can be seen that the unit in the anti-transmission phase shift variations model of 8.6~12.5GHz from Fig. 5 (b)
It encloses larger (more than 360 degree), therefore the cross-shaped oscillator unit of four layers of dielectric-slab structure is selected to adjust anti-transmission phase.
Fig. 6 give bottom end load double annulus frequency-selective surfaces cross-shaped oscillator unit anti-transmission coefficient amplitude and
Phase with frequency situation of change.From Fig. 6 (a) as can be seen that at low-frequency range (8.5~10GHz), the reflection coefficient of the unit
Amplitude is totally reflected most of incident electromagnetic wave 0.9 or more；At high band (11~12.5GHz), the transmission system of the unit
Number amplitude is 0.9 or more, and to most of incident electromagnetic wave total transmissivity, therefore the unit can realize anti-transmission by switching frequency
The transformation of characteristic.From Fig. 6 (b) as can be seen that anti-transmission phase shift variations range of the unit in 8.5~12.5GHz is larger (super
Cross 360 degree), therefore the unit can be used to adjust anti-transmission phase.So loading double annulus frequency-selective surfaces using bottom end
Cross-shaped oscillator unit, can not only realize the transformation of anti-transmissison characteristic by switching frequency, but also can be used to adjust anti-transmission phase
Position meets the internal performance requirement of Multifunctional planar sky feedback array element.
In the range of Fig. 7 gives 9~12.5GHz, bottom end loads the cross-shaped oscillator unit of double annulus frequency-selective surfaces
Anti- transmission coefficient amplitude and phase with oscillator length L situation of change.From Fig. 7 (a) as can be seen that with oscillator length L
11.5mm is changed to from 7mm, reflection coefficient amplitude of the unit in 9,10GHz is greater than 0.9, and unit is totally reflected incidence wave at this time；
The transmission coefficient amplitude of 11GHz is 0.7 or so, and unit is to incidence wave half reflection, half transmitting at this time；12,12.5GHz transmission is saturating
Coefficient amplitude is penetrated 0.9 or more, unit is to incidence wave total transmissivity at this time.From Fig. 7 (b) as can be seen that with oscillator length L from
7mm changes to 11.5mm, unit 9~12.5GHz anti-transmission phase variation range at 300 degree or more, and different frequency
The phase curve approximation keeping parallelism at place shows good anti-transmission phase coherence of changing trend.Therefore, using change ten
The method of word oscillator length L not only can guarantee that the unit can show (anti-) in high (low) frequency and penetrate characteristic, but also can ensure that this
Have anti-transmission phase variation range in the wider frequency band of unit, also meets anti-transmission integrated multi-functional plane sky feedback array
The technical requirements of unit.
Since the path of feed antenna to array each unit is different, so existing between each unit by path difference institute
Caused by phase difference.In order to make array of designs each unit keep same phase, the present invention to each unit on array ten
Word oscillator length L is adjusted, and compensates the phase differential between each unit.
Since Vivaldi antenna has the advantages of broadband, end-fire；The present invention is using Vivaldi antenna as transmission battle array
The feed of antenna.Its structure is as shown in Figure 8.
It can be seen in figure 9 that plane sky feedback array antenna of the invention realizes high-gain spoke at each frequency
Ejected wave beam.At 9GHz, 10GHz, the greatest irradiation direction of the array antenna be it is preceding to, gain respectively reach 17.9dB and
18.2dB shows the function of plane reflection array antenna；At 10.8GHz, the forward and backward of the array antenna is maximum
Radiation direction, gain reach 16.2dB, show the function of bidirectional radiation；At 11,12,12.5GHz, the array antenna is most
Large radiation direction be it is backward, gain respectively reaches 15.9dB, 19.2dB and 17.9dB, shows the function of plane transmission array antenna
Energy.Therefore, Fig. 9's the result shows that, array antenna of the invention realized at low frequency before to high-gain radiate, in intermediate frequency
Place realizes bidirectional radiation, radiates after high frequency treatment realizes to high-gain, can be realized by frequency error factor to the array day
The flexible modulation of the greatest irradiation direction of line.More specifically, array antenna proposed by the present invention shows to put down in low-frequency range
