摘要：
A dual-polarized lower band (LB) antenna element is proposed in this letter. A pair of vertical arms and a pair of horizontal arms are designed with two cross Gamma-shaped feeding lines together for +/- 45 degrees polarizations. The sleeve arm can suppress the scattering for high-frequency electromagnetic wave and have almost negligible effect on low frequency. Meanwhile, unobstructed space for placing the higher band (HB) elements is reserved with surrounded scheme. The dual-band antenna (DBA) with four HB elements operating from 1.46-2.43 GHz and one LB element operating from 0.65-1.11 GHz is designed and fabricated. The simulated and measured results show that the stable radiation performance and low mutual interference for LB and HB elements are achieved in DBA.
