| 摘 要： | 应用LTCC技术设计了4×4的宽带阵列天线,通过在多层贴片结构中引入空气腔、匹配过孔以及金属环等结构有效拓展天线的带宽,提高了辐射效率.馈电网络与主贴片间用内层地板分隔,有效地抑制了背向辐射.仿真结果表明,阵列天线在25.2-31.2GHz的频带内回波损耗低于-10dB,相对带宽达21.4%,峰值增益为16.84dB,...

| Abstract: | A 4×4 wideband array antenna is designed based on low temperature co-fired ceramic(LTCC) technology.Through introducing air cavities,matching through-holes and metal rings in multilayer stacked patch structure,bandwidth and radiation efficiency of the antenna get improved.Feeding network and main patch are separated by inner substrate,which can suppress backward radiation effectively.Simulation results show that within frequency range of 25.2 to 31.2 GHz,return loss of the array is better than-10dB,relative bandwidth is up to 21.4%,and peak gain is 16.84dB.Dimensions of whole antenna array are 50×50×1.153mm3. |
