AbstractA 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. 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.

A frequency‐reconfigurable slot antenna designed using metasurface (MS) is proposed in this paper. The frequency‐reconfigurable metasurfaced (FRMS) antenna is composed of a simple slot antenna and a MS, both having a circular shape with the same diameter of 50 mm (equivalent to 0.5λ 0 where λ 0 is the operating wavelength in free space) and implemented using planar technology. Polarization reconfigurable slot antenna for 5.8 GHz ... 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.
