摘　　要：设计了一种基于低温共烧陶瓷技术(LTCC)的Ka波段喇叭天线阵列。该天线利用LTCC工艺的特点,采用了通孔来实现波导脊的设计,使得脊喇叭天线得以实现。喇叭口处设计了介质块进行相位修正,使得天线获得较宽的带宽。利用微带线和介质集成波导(SIW)进行馈电,组成4×1的阵列进行仿真,阵列带宽为21.7%,方向图在频段内稳定,适合用于各种集成端射天线辐射系统。A Ka-band ridge horn antenna array is designed based on the low temperature co-fired ceramic（ LTCC）. Based on the features of the LTCC technology,the waveguide ridge is designed with the metal holes to realize the ridge horn antenna. The dielectric block is adopted at the antenna aperture for the phase correction to make the antenna obtain wide bandwidth. Fed by the micro-strip line and the substrate integrated waveguide（ SIW）,the 4 × 1 array is formed and simulated,which indicates that the array bandwidth is 21. 7 %,the pattern is stable in the frequency band,and it is applicable to various integrated end-fire antenna radiation systems.
