摘要

提出了一种三层发射聚焦梯度元表面(FGMS)，可实现8.2 GHz至10 GHz的宽带增益增强。宽带发射FGMS元件具有高于0.7的高发射效率，并且在工作频带内具有平坦和线性趋势的[0,2 π]相位范围。FGMS可以将球面波转化为平面波。将工作频率分别为8.2 GHz、9.1 GHz和10 GHz的3个贴片天线作为球波源置于宽带FGMS的焦点处，构建宽带平面透镜天线系统。仿真增益为15.44 dBi，比裸贴片天线在10 GHz时的仿真增益高7.51dB，具有良好的sll和波束宽度。然而，它提高了裸贴片天线在宽工作频带的增益。最后，制作了FGMS和贴片天线并进行了测量。实测结果与模拟结果吻合较好。

Gain Enhancement Planar Lens Antenna based on Wideband Focusing Gradient Meta-surface

A three-layered transmitting focusing gradient meta-surface (FGMS) has been proposed, which can achieve broadband gain enhancement from 8.2 GHz to 10 GHz. The element of broadband transmitting FGMS has high transmitting efficiencies that over 0.7 and achieve [0, 2π] phase range with a flat and linear trend in the operating band. The FGMS can transform the spherical waves into plane waves. Three patch antennas working at 8.2 GHz, 9.1 GHz, and 10 GHz respectively are placed the focus of broadband FGMS as the spherical-wave source to build a broadband planar lens antenna system. It achieves a simulation gain of 15.44 dBi which is 7.51dB higher than that of the bare patch antenna at 10 GHz with satisfying SLLs and beamwidths. However, it enhanced the gain of the bare patch antenna in a wide operating band. Finally, the FGMS and the patch antenna are fabricated and measured. The measured results are in good agreement with the simulations.

期刊介绍： The ACES Journal is devoted to the exchange of information in computational electromagnetics, to the advancement of the state of the art, and to the promotion of related technical activities. A primary objective of the information exchange is the elimination of the need to "re-invent the wheel" to solve a previously solved computational problem in electrical engineering, physics, or related fields of study. The ACES Journal welcomes original, previously unpublished papers, relating to applied computational electromagnetics. All papers are refereed. A unique feature of ACES Journal is the publication of unsuccessful efforts in applied computational electromagnetics. Publication of such material provides a means to discuss problem areas in electromagnetic modeling. Manuscripts representing an unsuccessful application or negative result in computational electromagnetics is considered for publication only if a reasonable expectation of success (and a reasonable effort) are reflected. The technical activities promoted by this publication include code validation, performance analysis, and input/output standardization; code or technique optimization and error minimization; innovations in solution technique or in data input/output; identification of new applications for electromagnetics modeling codes and techniques; integration of computational electromagnetics techniques with new computer architectures; and correlation of computational parameters with physical mechanisms.
