摘　　要：针对移动终端设备本身体积小,对应用于移动终端的天线需要满足体积小、剖面低、容易和载体共形等要求,提出了一种具有双层介质板结构的双极化多层微带天线的模型,该模型带有接地板,容易和载体共形。天线单元带宽范围为1890～2200MHz,回波损耗优于-33dB。水平极化增益和垂直极化增益均为8.2dB,实现了高增益、双极化的特性。Aimed at the required small volume, low profile, conformability with existing structures of mobile terminal equipment, this paper proposes a dual - polarized and multilayered micro - strip antenna which can？easily be integrated with the carrier. The antenna elements＇ bandwidth is 1890 - 2200MHz, return loss is better than -33dB, and horizontal polarization and vertical polarization gain are 8.2dB achieving the features such as high gain and dual - polarization.
