摘要

为了提高毫米波贴片天线的带宽和增益，提出了人工磁导体结构。重点分析和设计了多层层压波导(LWG)低损耗阵列馈电网络和多层t型分频器。采用低温共烧陶瓷(LTCC)工艺设计了毫米波天线阵列的整体结构，其中集成了馈电网络以及LWG和矩形波导(RWG)之间的紧凑转换。2×2阵列的模拟带宽为11.43%，远高于PEC平面上的参考阵列。最大增益可达12.9 dBi，并能观测到稳定的辐射方向图。

A 2×2 wideband and high-gain Ka- band LTCC patch antenna array using aritificial magnetic conductor structures

The artificial magnetic conductor structures (AMCs) is proposed to enhance the bandwidth and gain of a millimeter-wave (mmW) patch antenna. A multi-layer laminated waveguide (LWG) low-loss array feeding network and the multi-layer T-type divider are specially analyzed and designed. The overall structure of an mmW antenna array using AMCs is designed in low temperature co-fired ceramics (LTCC) process in which the feeding network and compact transition between LWG and rectangle waveguide (RWG) are integrated. The simulated bandwidth of the 2×2 array is 11.43% which is much larger than that of the reference array on PEC plane. The maximum gain can reach 12.9 dBi while the stable radiation pattern can be observed also.
