Embodiment
For more understanding technology contents of the present invention, be described as follows especially exemplified by a preferred embodiment.
As shown in Figure 2, circular polarization aerial 10 of the present invention comprises following elements: antenna element 12,14,16, and 18, and the structure of each antenna element is all identical, and carries out the example explanation with antenna element 12, but not as limit.As shown in Figure 3, antenna element 12 more comprises: diaphragm 22, microstrip antenna (comprise supporting layer 24 and place the paster 26 of supporting layer 24 upper surfaces), center have cuboid slotted eye 30 substrate 28, and upper surface have the substrate 32 that cross slotted eye 34 and lower surface have metal call wire 36.Wherein, upper surface has the substrate 32 that cross slotted eye 34 and lower surface have a metal call wire 36 and also can be used as slot antenna, and can form the slotted eye coupling device have the substrate 28 of cuboid slotted eye 30 in conjunction with the center after.Therefore, the putting in order in regular turn and to be diaphragm 22, microstrip antenna, and slotted eye coupling device from top to bottom of said elements, and be described as follows in regular turn:
It is the dielectric film of prepreg or film or the paper that other nonmetallic materials are made that supporting layer 24 can be paper, candy wrapper, title material, and the upper surface of supporting layer 24 is equipped with paster (patch) 26, paster 26 is preferably Copper Foil, and the preferable upper surface that is pasted on superficial layer 24, its size can be 10mm*10mm.The big I of paster 26 according to user's actual demand with the decision, not as limit.Supporting layer 24 can provide the function of microstrip antenna in conjunction with paster 26.
It is No. four power dividers (4-waypowcrdivider) that power disperser 20 is preferably, and the one end is electrically connected to power connection wire 11,13,15 respectively, reaches 17, and the other end is electrically connected to demodulator.The function of power divider 20 is to carry out the distribution of power, makes the power amplitude part can be uniformly distributed to each power connection wire and antenna element.Because the manufacture method of circular polarization aerial 10 of the present invention is similar to the method for making general printed circuit board, so manufacture method is simple and with low cost.
Therefore, circular polarization aerial 10 of the present invention can be by receiving polarized signal by microstrip antenna, and receive this polarized signal by the slotted eye coupling device, and its lotus root is bonded to metal call wire 36, again by output line 42 these polarized signals of output of metal call wire 36.Thus, the user only need adjust the position of antenna element, and cooperate phase place can receive the Circular Polarisation signal, for example, make antenna element 12,14,16, and the relative position position of 18 signal input line 38 is respectively 0,90,180, and 270 degree, cooperate power connection wire 11,13,15 again, reach 17 length, antenna element 12,14,16, and 18 in time phase differences also are 0,90,180, and the polarized signals of 270 degree, reach the purpose that circular polarization aerial 10 of the present invention can receive the figure polarized signal.In addition, antenna element 12,14,16, and 18 improvement that can be considered the traditional antenna element only also apply to antenna element 12,14,16, reach the characteristic that will have higher frequency range on 18 with the pivoting mechanism of distributor circuit general.In addition, the user can pass through by the energy regenerative order of arranging metal call wire 36, and realizes the purpose that dextrorotation or left-handed polarization signal receive.
As shown in Figure 4, circular polarized array antenna 50 of the present invention is made up of a plurality of circular polarization aerial 10 of the present invention, for example: 4,16,64 etc., be preferably by 4 circular polarization aerials 10 of the present invention and formed, but not as limit, and respectively by by power connection wire 52,54,56, and 58 and produce electrically connects with power disperser 60.Because the operation principles of circular polarized array antenna 50 of the present invention is identical with circular polarization aerial of the present invention 10, so it is bright not speak more.Well imagine ground, circular polarized array antenna 50 of the present invention has circular polarization aerial 10 the more of the present invention, the receiving ability of its polarized signal is then better, as shown in Figure 5, the receiving ability of polarized signal with circular polarized array antenna of the present invention 50 of 64 circular polarization aerials 10 is better than the circular polarized array antenna of the present invention 50 of 16 circular polarization aerials 10 and 4 circular polarization aerials 10.In addition, circular polarized array antenna 50 of the present invention has circular polarization aerial 10 the more of the present invention, and the yield value of the loss of turning back is lower, and circular polarized array antenna 50 promptly of the present invention receives the Circular Polarisation signal more easily.As shown in Figure 6, in this section of 11GHz to 12GHz frequency band, the gain of the loss of turning back with circular polarized array antenna of the present invention 50 of 64 circular polarization aerials 10 of the present invention can be satisfied user's demand of yield value for the loss of turning back in this frequency band.
Circular polarization aerial of the present invention and traditional circular polarization aerial one of do not exist together and to be only also to apply to antenna individual elements antenna element 12,14,16, reach 18 with the pivoting mechanism of distributor circuit general, and this pivoting mechanism is to be that every (four corner location of cross slotted eye) form through quarter-wave discontinuous place by microstrip antenna by coupling position.Partly then cooperate complex power connecting line and power disperser to form circular polarized array antenna 50 of the present invention at distributor circuit, the arrangement of cuboid slotted eye more reduces dielectric loss, make circular polarized array antenna 50 of the present invention not only can receive the Circular Polarisation signal, has the good signal receiving ability, the characteristic that has more low cost and make easily is so can satisfy the demand of user in the antenna that receives the Circular Polarisation signal.
The foregoing description only is to give an example for convenience of description, and the interest field that the present invention advocated should be as the criterion so that claims scope is described certainly, but not only limits to the foregoing description.
