Abstract: A frequency-reconfigurable slot antenna using metasurface (MS) is proposed. Two identical anisotropic MS layers are loaded on top of a slot to achieve the frequency reconfigurability. The MS layer is composed of a periodic arrangement of I-shaped metallic inclusions placed in both the horizontal and vertical directions. ISSN: 2278-0181 PECTEAM - 2K18 Conference Proceedings ... Abstract—A frequency-reconfigurable antenna designed using metasurface (MS) to operate at around 5 GHz is studied and proposed. The frequency-reconfigurable metasurfaced (FRMS) antenna is composed of a simple circular patch antenna and a circular MS with the same diameter of 40 mm and implemented using planar technology. The MS is placed Frequency Reconfigurable Antenna Design Using Metasurface II. Design of Frequency Reconfigurable Mestsurfaced Antenna The FRMS antenna proposed here consists of a patch antenna (as the source antenna) and a metasurface (MS). For easy reconfigurable operation of the antenna, the patch antenna and MS are designed to have a circular shape and occupy the same area. Frequency Reconfigurable Antenna Using Metasurface for ...

Sep 01, 2011 · A planar polarization-reconfigurable metasurfaced antenna (PRMS) designed using metasurface (MS) is proposed. The PRMS antenna consists of a planar MS placed atop of and in direct contact with a planar slot antenna, both having a circular shape with a diameter of 78 mm (0.9 $\lambda_{0}$ ), making it compact and low profile. Planar wideband circularly polarized metasurface-based performance of the slot antenna is studied under different configurations shown in Figure 3(a), and the results are shown in Figure 3 (b) and (c). Antenna I is a conventional slot antenna without a metasurface. Antenna II is a slot antenna using a conventional metasurface composed of 4 × 4 square patches. Antenna III is the proposed structure.

Frequency‐reconfigurable slot antenna with wide‐tuning
Recently, metamaterial, as a novel method, is applied in the design of the polarizationreconfigurable antenna [3] [4]. In [3], a slot antenna using 2D metasurface can be reconfigured to operate in left-handed CP (LHCP), right-handed CP (RHCP) and linear polarization (LP) by mechanically rotating the metasurface.
