摘要

本文提出了一种工作在ka波段(32 ~ 38GHz)的相控阵天线阵列。该天线为偶极子天线，介质层为低温共烧陶瓷(LTCC)。扫描至30°时，未对孔径进行过采样，e面、d面和h面有源vswr分别小于2.25、2.75和2.57。仿真结果表明，该天线阵的扫描角范围为-30°~ +30°，增益衰减小，有源驻波比好。在35GHz时，天线阵列的模拟最大增益约为24.6dBi。所提出的相控阵天线在雷达系统中具有良好的应用前景。

A LTCC Antenna Array in Ka- Band for Beam Scanning Applications

In this paper, an antenna array for phased array antenna operating in Ka-band (32 - 38GHz) is presented. The proposed antenna is dipole, and the dielectric layer we used is low-temperature co-fired ceramic (LTCC). The active VSWRs of E-plane, D-plane and H-plane are less than 2.25, 2.75 and 2.57 while scanning to 30°, without oversampling the aperture. An antenna array with 64 elements is simulated, and the simulation results show that the proposed antenna array has a scanning angle from -30° to +30° with low gain decrease and good active VSWR. The simulated maximum gain of the antenna array is about 24.6dBi at 35GHz. The proposed phased array antenna has a good application prospect in radar systems.
