提出了一种基于人工磁导体（AMC）结构的低温共烧陶瓷（LTCC）天线辐射性能改善方法。设计了一种基于AMC结构的毫米波LTCC贴片天线，实现了26%的宽带宽、8.27dBi的高增益和86.2%的高辐射效率。在此基础上，研制了一种4 × 4阵列天线。提出了一种低损耗的多层叠层波导功分器作为天线阵的馈电结构。该阵列的仿真和测量结果吻合良好，并表现出良好的和稳定的性能，在13.96%的匹配带宽，19.1 dBi的高增益，和平坦的增益响应与2 dB的变化。此外，效率可以达到63.1%，这是高于其他设计在文献中。在34至37 GHz的宽频带上实现了超过45%的非常高的效率。
A novel method based on an artificial magnetic conductor (AMC) structure is presented to improve radiation performances of low-temperature co-fired ceramics (LTCC) antennas. A millimeter-wave (mmW) LTCC patch antenna using AMC structures is designed, achieving a wide bandwidth of 26%, a high gain of 8.27 dBi, and a high radiation efficiency of 86.2%. Based on the antenna element, an 4 × 4 array with an AMC is developed. A low loss multilayer laminated waveguide (LWG) power divider is proposed to feed the array. Simulation and measurement results for the proposed array are in good agreement, and demonstrate a good and stable performance in terms of 13.96% matching bandwidth, high gain of 19.1 dBi, and flat gain response with variation of 2 dB. Furthermore, the efficiency can reach 63.1% which is higher than other designs available in the literature. A very high efficiency of more than 45% is achieved across a wide frequency band from 34 to 37 GHz.
