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.
