Embodiment
Below in conjunction with accompanying drawing 1-15, double polarization array antenna and the radiating element thereof of each embodiment of the utility model are described further.
A kind of double polarization array antenna, be arranged in order and be provided with some radiating elements on its reflecting plate 30, and herein some can be that odd number can be also even number.Each radiating element is dual-polarization radiating unit, and it has the radiating doublet of two pairs of orthogonal thereto installations, and every a pair of radiating doublet is for the signal of radiation one polarization.
As illustrated in fig. 1 and 2, structure and the shape of at least one radiating element wherein are specific as follows:
Defining this radiating element is the first radiating element 10, the wherein a pair of radiating doublet of this radiating element 10 is for the signal of radiation the first polarization, take ± 45 ° of words that dual-polarization radiating unit is example, it can be the signal of radiation+45 ° polarization, defining this is first pair of radiating doublet 11 to radiating doublet, and the position at these first pair of radiating doublet 11 place is the first space layer H1.Another of this radiating element 10 be the signal for radiation the second polarization to radiating doublet, take ± 45 ° of words that dual-polarization radiating unit is example, it can be the signal of radiation-45 ° polarization, defining this is second pair of radiating doublet 12 to radiating doublet, and the position at these second pair of radiating doublet 12 place is second space layer H2.This space layer H1, H2 are illusory, in order to embody shape, define, and it does not have visual structure to show in the drawings.
Take reflecting plate 30 as benchmark, the first space layer H1 on the vertical direction of reflecting plate 30 at least partly higher than second space layer H2, be specifically as follows: this first space layer H1 and second space layer H2 separate fully on the vertical direction of reflecting plate 30, and the first space layer H1 integral body is higher than second space layer H2; Perhaps the first space layer H1 and second space layer H2 partly overlap on the vertical direction of reflecting plate 30, and the end face of the first space layer H1 is higher than the end face of second space layer H2.
This first radiating element 10 comprises that Ba Lun 13 specifically can be integrated column for two pairs of radiating doublets 11,12 being provided to the Ba Lun 13 of physical support.On this Ba Lun 13, the bisector position of two crossing angles that produce of adjacent radiation oscillator has extended to form crack 132 downwards, this crack 132 is for the conversion from unbalanced coaxial cable feed to the feed the radiating doublet of balance, and the length in each crack 132 is about 1/4th operating frequency wavelength of central task frequency.
On this Ba Lun 13, the zone between two adjacent cracks 132 is Ba Lun arm 131.Be provided with feed port 135 on Ba Lun arm 131, two contour settings of feed port 135 of same polarization, couple together by the feed tab 134 that plays the feed effect between the feed port 135 of same polarization, cushion with the dielectric piece between feed tab 134 and Ba Lun arm 135, play buffer action.The feed port 135 of the first polarization is higher than the feed port 135 of the second polarization, so connect the feed tab 134 of two feed port 135 of the first polarization higher than the feed tab 134 of the feed port 135 that connects the second polarization, the feed tab 134 of two polarization arranged in a crossed manner and on the vertical direction of reflecting plate 30 at intervals, the feed that can further reduce between two polarization of the first radiating element 10 is interfered.
