摘要

提出了一种ku波段双极化三角形天线阵。天线由垂直固定在铝腔上的两个正交放置的偶极子组成。偶极子是由两个相似的同轴馈线激发的。为了减小天线的整体尺寸，将偶极子元件弯曲，并在同轴馈线末端集成SMP接口。此外，在同轴的外导体上放置两个槽，以便更好地匹配阻抗。仿真和测试结果表明，在13.8GHz ~ 14.6 GHz工作频段内，天线电压驻波比小于1.65，天线隔离度大于39.4 dB。在中心频率为14.2GHz时，两个极化口天线阵列的增益分别为13.3dBi和13.7dBi。

Design of a Ku-band Highly-Integrated Dual-Polarized Dipole Antenna Array

A Ku-band dual-polarized triangular antenna array is proposed. The antenna is composed of two orthogonally placed dipoles which are vertically fixed on an aluminum cavity. The dipoles are excited by two similar coaxial feeders. In order to reduce the entire size of the antenna, the dipole element is bent and the SMP interface is integrated at the end of the coaxial feeder. Furthermore, two slots are placed on the outer conductor of the coaxial for a better impedance matching. Simulation and test results show that the antenna voltage standing wave ratio (VSWR) is less than 1.65, and the antenna isolation is greater than 39.4 dB in the operating frequency band of 13.8GHz to 14.6 GHz. At the center frequency of 14.2GHz, the gains of the antenna array of the two polarization ports are 13.3dBi and 13.7dBi, respectively.
