Dual circularly polarized phased array antenna

摘要: A phased array antenna is provided by stacking two PC boards in a superimposed relationship above the base of housing for antenna. Each these contain therein symmetrical arrangement photo etched or printed mat-strip power division networks and plurality radial arrangements each including dipole elements having given angular therebetween. The on one board are orthogonally related to other board. RF switching means control that connected network so phase dual circularly polarized radiation pattern can be controlled quantized steps determined said relation. ground plane lower upper parallel, space conductive members superimposed, parallel with arrangements. fed double ended balun. baluns turn from quadrature hybrid.
