The novel printed crossed 2times2 dipole array is proposed for broad axial ratio (AR) bandwidth. The broad bandwidth of axial ratio is due to a parasitic dipole crossing over the original dipole that is driven by a semi-rigid coaxial feed with the characteristic impedance of 75 Omega. The crossed dipole, a unit element of the dipole array proposed in this paper, can produce a broad circularly polarized...
