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 ... Antenna II is a slot antenna using a conventional metasurface composed of 4 × 4 square patches. Antenna III is the proposed structure. For fair comparison, the design parameters of Antennas I and II are chosen to be the same as those of the single element. Without the metasurface, Antenna I is a lP slot antenna with the resonance Frequency Reconfigurable U-Shaped Microstrip Patch Antenna ...

Reconfigurable Dipole Antenna - IEEE Xplore - mafiadoc.com 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. I have done a seminar on frequency reconfigurable antenna using... I have done a seminar on frequency reconfigurable antenna using metasurface. What thesis topic related to antennas should I select? ... What is the difference between slot antenna and patch antenna? Can you suggest any good research topic in antenna design? What is the relation between antenna length and frequency?
Reconfigurable antennas have been used in the past 10 years for a variety of applications butPassive metasurfaces in most cases operate for a single functionality and at a single frequency or on aAn active metasurface allows integrating multiple functionalities into a single metasurface, and...

In this paper, a CPW-fed circular polarization reconfigurable slot antenna is proposed. By simply changing the bias status of two PIN diodes through a T-type bias device, the antenna can work as two independent inverted L-shaped slots, and realize reconfigurable performances.
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.
