1. dual polarized antenna comprises:

  • a radiating curtain, a reflection ground plate and four supportive conductors, wherein,The two ends of every supportive conductors are connected with the reflection ground plate with radiating curtain respectively, described four supportive conductors are right-angled intersection in twos relatively and arrange parallel to each other again, and perpendicular to radiating curtain and reflection ground plate, these four supportive conductors have been formed two vertical baluns, wherein, two supportive conductors that are on the crossing conductor diagonal are formed a balunDescribed radiating curtain by four identical and conductor loops that include one group of transition symmetry line respectively form, these conductor loops have line of symmetry, and be joined to one another by this way, be that radiating curtain is a cross-like, and in this array, include a cross slit, each conductor loops constitutes a branch of crossing conductor and a branch of cross slit, crossing conductor has four line of symmetries, article two, be the line of symmetry of conductor loops, two other is the diagonal of crossing conductor, the top of every supportive conductors is connected with a corner point of right-angled intersection place, and the bottom is connected on the corresponding ground plate, described corner point is a drift angle that is formed by the per two transition symmetry lines on the radiating curtain, and is on two diagonal of crossing conductorFirst electricity feedback network is connected on the crossing conductor, pass on article one diagonal of cross slit, second electricity feedback network is connected on the crossing conductor, pass on the second diagonal of cross slit, radiating curtain is activated in this way, its radiation mode is two mutually perpendicular electromagnetic fields, and this electromagnetic field has and is set the E vector parallel with the crossing conductor diagonal.
