In this paper, an electromagnetically transparent dipole working at the low-band (LB, 1.7-2.5 GHz) is proposed to simultaneously suppress the cross-band scattering and coupling to the high-band (HB, 4.4-5.0 GHz) antenna in a dual-band array. Dual-functional patches with vias are loaded on radiating arms of the LB dipole, which can introduce reversed induced-currents at the HB to restore the deteriorated HB radiation patterns and improve cross-band isolations at the HB. After the loading, HB patterns are well recovered, showing great consistency with the patterns of the HB dipoles operating alone. The transmission coefficients between the LB and HB ports are also greatly reduced.
