And synchronizing linkage;
Eletricity adjusting directional intelligent antenna has the individual vertical subarray of N (N 〉=2) to form, each vertical subarray comprises the individual radiating element of M (M 〉=2) and several power distributing networks, each radiating element is arranged on the same straight line, be connected with power distributing network, feeder cable connects each power distributing network to phase shifter.Have a down dip in order to realize that antenna is transferred in the vertical plane continuous electric, at first all antenna radiation units with each vertical subarray i (i=1,2...N) encourage different amplitude, phase place by phase shifter, and then by synchronizing linkage with each group phase shifter synchronous interaction, respectively organize phase shifter and can export identical phase place simultaneously to reach, realize that N (N 〉=2) array antenna subarray has a down dip synchronously at vertical plane.Main feed port with all vertical subarrays is connected to calibration network 1 simultaneously, realizes the calibration of antenna amplitude, phase place.
All radiating elements of subarray i (i=1,2...N) are encouraged different phase place Φ by phase shifter, reach the purpose that changes each antenna radiation unit current feed phase, thereby the continuous electric that has realized eletricity adjusting directional intelligent antenna has a down dip.Its principle is as shown in Figure 2:
For the subarray i (i=1,2...N) that is spaced the individual radiating element oscillator of M (M 〉=2) for d, when the phase place of adjacent cells is etc. when evenly distributing mutually, the maximum wave beam of antenna is formed at the normal direction dead ahead.When the phase place of adjacent radiation unit differed Φ successively, maximum wave beam was formed at θ 0Direction in space.(differ be defined as Φ= 2 π/ λ* d*sin θ 0Wherein: λ is that operation wavelength, d are center distance, the θ of adjacent radiation unit in the same subarray 0Be angle of declination).
For the primary radiation wave beam that guarantees each vertical subarray can constant amplitude in the dead ahead with superimposed, so that satisfy different sector pattern, must satisfy having a down dip synchronously of each vertical subarray i (i=1,2...N), adopt synchronizing linkage with the phase shifter cascade for this reason, make the same port of respectively organizing phase shifter can export same phase simultaneously.Synchronizing linkage can be by the phase shifter of driver element as each vertical subarray i (i=1,2...N) of one group of driven by motor, or organize motor is realized phase shifter by synchronous circuit synchronous interaction more.Graduated scale links to each other with synchronizing linkage, can show the antenna downtilt angle.
