摘要

提出了一种高隔离度的宽带双极化印刷偶极子天线。所提出的天线由水平基板、水平接平面和两个垂直基板组成。所述两个垂直基板垂直安装在所述水平基板和所述水平接平面之间。四个三角形贴片对称地印在上水平基材的底面上。另外，四个垂直矩形块与三角形块具有相同的对称中心，分别与三角形块和地平面相连。四个矩形贴片中的每两个都印在垂直基板的一侧，而集成平衡轮印在另一侧。该天线在52%的阻抗带宽(VSWR< 1.5)下实现了39dB以上的端口隔离。该天线易于扩展为阵列，可用于下一代IMT-Advanced通信中的基站天线。

Wideband dual-polarized printed dipole antenna with high isolation

A wideband dual-polarized printed dipole antenna with high isolation is proposed in this paper. The proposed antenna is composed of a horizontal substrate, a horizontal ground plane and two vertical substrates. The two vertical substrates are mounted orthogonally between the horizontal substrate and the horizontal ground plane. Four triangular patches are printed on the bottom side of the upper horizontal substrate symmetrically. Moreover, four vertical rectangular patches, which have the same center of symmetry as the triangular patches, are connected to the triangular patches and ground plane, respectively. Each two of the four rectangular patches are printed on one side of each vertical substrate that an integrated balun printed on the other side. The proposed antenna achieves a port isolation higher than 39dB over 52% impendence bandwidth (VSWR<;1.5). The antenna is easy to be extended to arrays and can be used for base station antennas in the next generation IMT-Advanced communications.
