Abstract
The utility model discloses a double-band corner reflector antenna, comprising a metal corner reflector, frequency I band sleeve oscillators and frequency II band sleeve oscillators. The frequency I band sleeve oscillators and the frequency II band sleeve oscillators are alternately distributed on the same straight line along the bottom of the metal corner reflector. In the double-band corner reflector antenna, the sleeve oscillators in two frequency bands are integrated on the corner reflector, so that space and cost are greatly reduced under the condition of keeping antenna performances essentially unchanged, and the antenna can operate in two frequencies.
Description
Technical field
The utility model relates to a kind of antenna technology, relates in particular to a kind of two-band corner reflector antenna.
Background technology
Existing corner reflector antenna has only a frequency range, if in different frequency range work, just need multiple antenna, increasing antenna needs bigger installing space undoubtedly, and the heavy burden of carrier is increased, and the also corresponding raising of its cost.
The utility model content
The utility model proposes a kind of two-band corner reflector antenna, its structure is: it comprises: metal corner reflector, I frequency range sleeve oscillator and II frequency range sleeve oscillator, I frequency range sleeve oscillator and II frequency range sleeve oscillator are arranged alternately on the same straight line along metal corner reflector bottom.
The arrangement mode of sleeve oscillator is: single I frequency range sleeve oscillator and single II frequency range sleeve oscillator are arranged in metal corner reflector bottom, perhaps, the array of the array of I frequency range sleeve oscillator composition and II frequency range sleeve oscillator composition is arranged alternately in metal corner reflector bottom.
II frequency range sleeve oscillator top is connected with a little metallic plate, and plane, little metallic plate place is axially vertical with II frequency range sleeve oscillator.
The frequency range of II frequency range sleeve oscillator is higher than I frequency range sleeve oscillator.
The subtended angle of metal corner reflector is 90 °.
Useful technique effect of the present utility model is: the sleeve oscillator of two frequency ranges is integrated on the secondary metal corner reflector, is guaranteeing to have saved space and cost greatly under the constant substantially situation of antenna performance, make the antenna can be simultaneously two frequency range work.

Embodiment
At the problem of describing in the background technology, the utility model proposes a kind of integrated two-band corner reflector antenna of two working frequency range, its structure is: it comprises: metal corner reflector 1 (subtended angle of metal corner reflector 1 is 90 °), (I frequency range sleeve oscillator 3 becomes aerial radiation source 2 with II frequency range sleeve oscillator 4 mutual group to I frequency range sleeve oscillator 3 with II frequency range sleeve oscillator 4,2 sleeve oscillators by a kind of frequency range in aerial radiation source of conventional corner reflector antenna constitute), I frequency range sleeve oscillator 3 and II frequency range sleeve oscillator 4 are arranged alternately on the same straight line along metal corner reflector 1 bottom; The arrangement mode of sleeve oscillator is: single I frequency range sleeve oscillator 3 and single II frequency range sleeve oscillator 4 are arranged in metal corner reflector 1 bottom; Perhaps, the array of the array of I frequency range sleeve oscillator 3 compositions and II frequency range sleeve oscillator 4 compositions is arranged alternately in metal corner reflector 1 bottom; II frequency range sleeve oscillator 4 tops are connected with a little metallic plate 7 (connecting by metal), and plane, little metallic plate 7 place is axially vertical with II frequency range sleeve oscillator 4.
The working frequency range of II frequency range sleeve oscillator 4 is higher than I frequency range sleeve oscillator 3 (this arrangement is a kind of preferred form that the inventor selects).
As a secondary complete antenna, the utility model structure also includes: power division synthesizer (being the power splitter among Fig. 1), other external equipments such as mixer, I/O port; I frequency range sleeve oscillator 3 coaxial line 5 by a dotted line is connected on the power splitter, and II frequency range sleeve oscillator 4 is connected on the power splitter by solid coaxial line 6.The feed that power splitter is finished respectively height frequency range sleeve oscillator distributes and impedance matching, and the two-way after power splitter is handled converges signal and converges to the I/O port of antenna and be transferred to miscellaneous equipment (not giving unnecessary details in the literary composition) through mixer.
The utility model successfully is integrated in the sleeve oscillator of two frequency ranges on the one secondary metal corner reflector 1, and the impedance bandwidth of I frequency range sleeve oscillator 3 reaches 40%, gain 13dBi, and sleeve oscillator 4 impedance bandwidths of II frequency range reach 35%, gain 16dBi.Under the certain situation of the size of metal corner reflector 1, the main electrical performance indexes of sleeve oscillator of two frequency ranges is almost suitable with non-integrated one-segment sleeve oscillator index, this has saved the installing space (application on some car antenna is especially outstanding) of antenna greatly, provide cost savings, the cost performance of antenna is obviously improved.
