摘要

提出了一种用于增强偶极子天线增益的新型平面叠加层，并对其进行了建模和分析。叠层由两个紧挨着的平行短偶极栅格和偶极栅格之间的连续导线栅格组成。同时还研究了无线栅的情况。为了提取上覆层的透射和反射响应，建立了基于局部场法的解析模型。并与ansys - hfss预测结果进行了比较。为偶极子天线设计了一种有限尺寸的上盖，仿真结果表明，该上盖能显著提高天线的增益

Modelling and Analysis of Composite Antenna Superstrates Based on Grids of Dipoles and Wires

A new planar superstrate, proposed for the gain enhancement of dipole antennas, is modelled and analyzed. The superstrate consists of two closely located parallel grids of short dipoles and one grid of continuous wires in between the dipole grids. Also the situation when the wire grid is absent is studied. An analytical model based on the local field approach has been derived in order to extract the transmission and reflection responses of the superstrates. The responses have been compared with the results predicted by Ansoft-HFSS. A finite size superstrate has been designed for a dipole antenna, and the simulations show that a significant gain enhancement can be achieved with the proposed design
