Abstract

ABSTRACTIn this paper, a single-layered broadband circularly polarized MIMO antenna is presented for a 5 GHz wireless local area network (WLAN). The Metasurface is designed with an array of patches and these patches are excited by four uniform aperture CPW feed MIMO antennas. The stubs are added across the aperture and central patches at respective apertures are increased to achieve broad bandwidth. Truncated corner square patches are used for the metasurface to achieve circular polarization (CP). The CP MIMO antenna has achieved an impedance bandwidth of 33% (4.35 GHz-6.08 GHz), a 3 dB axial ratio (AR) bandwidth of 11.95% (5.18 GHz-5.8 GHz) and a gain of 8dBi.KEYWORDS: Broadband circular polarizationCPW fed aperturemetasurfaceMIMO antennatruncated corner square patch Disclosure statementNo potential conflict of interest was reported by the author(s).

基于超表面孔径CPW馈电的单层宽带圆极化MIMO天线

提出了一种用于5ghz无线局域网(WLAN)的单层宽带圆极化MIMO天线。metassurface设计了一组贴片阵列，这些贴片由四个均匀孔径CPW馈电MIMO天线激发。在光圈上增加存根，在各自的光圈上增加中央贴片，以实现更宽的带宽。在超表面上使用截断的角方块来实现圆偏振。该CP MIMO天线的阻抗带宽为33% (4.35 GHz-6.08 GHz)， 3db轴向比(AR)带宽为11.95% (5.18 GHz-5.8 GHz)，增益为8dBi。关键词:宽带圆偏振，cpw馈电孔径，超表面，emo天线，调谐角方形贴片披露声明作者未报告潜在利益冲突。

期刊介绍： Publishing eight times per year, Electromagnetics offers refereed papers that span the entire broad field of electromagnetics and serves as an exceptional reference source of permanent archival value. Included in this wide ranging scope of materials are developments in electromagnetic theory, high frequency techniques, antennas and randomes, arrays, numerical techniques, scattering and diffraction, materials, and printed circuits. The journal also serves as a forum for deliberations on innovations in the field. Additionally, special issues give more in-depth coverage to topics of immediate importance. All submitted manuscripts are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. Submissions can be made via email or postal mail.
