Abstract

In this study, we propose a high-efficiency, low-profile transmitarray (TA) antenna system and present an efficient design procedure by co-designing a multiport subarray antenna (MPSA) to perform as a feed source and the TA simultaneously. The proposed TA antenna supports dual slant polarization (SP). Furthermore, the concept of effective phase discontinuity (EPD) based on a mutual coupling coefficient is introduced for efficient TA design operation at short focal lengths to verify the effectiveness of the advanced unit cell (UC) arrangement with gain enhancement. A TE/TM superimposing method was applied to derive the UC response over the entire area of the aperture of the TA based on the response analysis of a rotated UC satisfying 90° rotational symmetry to TE/TM oblique incidence. The designed TA antenna exhibits a low profile of F/D ratio = 0.33 at a center frequency of 3.5 GHz and a high aperture efficiency (AE) of 37%. The measured results are also in good agreement with the simulation results, indicating that the proposed TA antenna system provides an effective design methodology for SP array antennas and low-profile high-gain systems.
用TE/TM叠加分析反映有效相位不连续的低轮廓高效发射阵列天线
在本研究中,我们提出了一个高效率、低轮廓的发射阵列(TA)天线系统,并提出了一个高效的设计过程,通过共同设计一个多端口子阵列天线(MPSA),同时作为馈电源和TA。该天线支持双斜极化(SP)。在此基础上,引入了基于互耦系数的有效相位不连续(EPD)概念,用于短焦距下的高效TA设计操作,验证了增益增强的先进单胞(UC)排列的有效性。基于满足90°旋转对称的旋转UC对TE/TM斜入射的响应分析,采用TE/TM叠加法推导了TA整个孔径范围内的UC响应。设计的TA天线在中心频率为3.5 GHz时具有F/D = 0.33的低轮廓和37%的高孔径效率(AE)。实测结果与仿真结果吻合良好,表明本文提出的TA天线系统为SP阵列天线和低轮廓高增益系统提供了一种有效的设计方法。
