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. Frequency‐reconfigurable monopole antenna with wide tuning ... The frequency‐reconfigurable antenna is studied, designed, and optimized using computer simulation. Measurement is used for verification of the simulation results. Results show that the antenna can be tuned from 2.69 to 3.0 GHz using Section I and from 2.39 to 2.62 GHz using both Sections I and II together.

Frequency Reconfigurable Antenna Design Using Metasurface
Frequency‐reconfigurable slot antenna with wide‐tuning ... 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. Design of Frequency-and Polarization-Reconfigurable ... A frequency- and polarization-reconfigurable antenna composed of a metasurface, a planar slot antenna, and a metallic reflector is proposed in this letter.

Reconfigurable antenna - Wikipedia A reconfigurable antenna is an antenna capable of modifying its frequency and radiation properties dynamically, in a controlled and reversible manner. In order to provide a dynamic response, reconfigurable antennas integrate an inner mechanism (such as RF switches, varactors, mechanical actuators or tunable materials) that enable the intentional redistribution of the RF currents over the ... Conformal dual-band textile antenna with metasurface for WBAN ... The metasurface in the form of an artificial magnetic conductor (AMC) plane is formed using a rectangular patch incorporated with a diamond-shaped slot to generate dual-phase response. This plane is then integrated with the planar slotted dipole antenna prior to its assessment in free space and bent configurations. A Port and Frequency Reconfigurable MIMO Slot Antenna for ...
