AbstractThis article studies the electrostatic response of a two-dimensional dielectric half-ellipse. A semianalytical method is presented for solving the polarizability of a half-ellipse as a function of its relative permittivity. The polarizability depends on the direction of incident field, and therefore, it is written as a dyadic with two perpendicular components. These are called series and parallel polarizability, and they are solved separately. The solution requires a series expansion of the potential function, and the coefficients must be obtained numerically, through an inversion of a finite matrix equation. Numerical results are presented for the polarizability components of the half-ellipse as functions of its geometry and permittivity.KEYWORDS: Laplace equationpolarizabilityelliptic coordinatesPEC AcknowledgementsWe would like to thank Dr. Henrik Kettunen for his expertise and valuable contribution to the theoretical analysis, especially during the initial studies.Disclosure statementThe authors declare that they have no known competing interests that could have appeared to influence the work reported in this paper.Additional informationFundingThe research is funded by Sapienza University of Rome, Italy.Notes on contributorsMehwish NisarMehwish Nisar conducted this research and drafted the manuscript, Ari Sihvola and HenrikWallén contributed to the theoretical and numerical analysis as well as in finalizing the manuscript.

AbstractAn optically transparent antenna fed by a coplanar L-probe is proposed in this paper. Indium-doped tin oxide (ITO) with a sheet resistance of 3.5 Ω/sq etched on a soda-lime glass substrate is used as radiation array and ground to achieve high optical transmittance. TM10 and TM20 modes are excited simultaneously to expand work bandwidth. The fabricated antenna achieves a –10 dB reflection bandwidth of 27.5% from 4.7 to 6.2 GHz with the overall size of 42 mm × 42 mm × 3.3 mm. Different from many antennas composed of ITO, the proposed antenna exhibits directional radiation patterns with the maximum realized gain of 4.6 dBi and the maximum efficiency of 61%. Meanwhile, the optical transmittance of the antenna can reach above 58%.Keywords: Optical transmittanceantennagainindium-doped tin oxide (ITO) Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported by the Shaanxi Natural Science Basic Research Project of Shaanxi science and Technology Office[No. 2023-JC-QN-0673]the National Natural Science Foundations of China[No. 61971340 and 62122061].Notes on contributorsPingle LiangPingle Liang received the B.E. degree in electronic and information engineering from Chongqing University, Chongqing, China, in 2021.

摘要本文提出了一种共面l型探头馈电的光学透明天线。将电阻为3.5 Ω/sq的铟掺杂氧化锡(ITO)蚀刻在钠石灰玻璃基板上作为辐射阵列和地面，以实现高透光率。同时激励TM10和TM20模式，扩大工作带宽。该天线在4.7 ~ 6.2 GHz范围内的反射带宽为-10 dB，为27.5%，整体尺寸为42 mm × 42 mm × 3.3 mm。与许多ITO构成的天线不同，该天线具有定向辐射方向图，最大实现增益为4.6 dBi，最大效率为61%。同时，天线的透光率可达58%以上。关键词:光学透射;天线;铟掺杂氧化锡(ITO)披露声明作者未报告潜在利益冲突。项目资助:陕西省科技厅自然科学基础研究项目[No. 1];国家自然科学基金项目[2023-JC-QN-0673];[61971340和62122061]。梁平乐，2021年毕业于中国重庆大学，获电子与信息工程学士学位。他目前在西安交通大学信息与通信工程学院攻读信息与通信工程硕士学位，中国西安。主要研究方向为光学透明天线和探地雷达天线。陈娟，出生于中国重庆。2008年获西安交通大学电磁场与微波技术博士学位。现就职于中国西安交通大学，任教授。主要研究方向为计算电磁学、微波器件设计等。
