[Invited Talk (Young Researcher)] Research on Mechanically Reconfigurable Reflectarray Antenna

Abstract (in Japanese) (See Japanese page) 
(in English) This work addresses the advantages of mechanically reconfigurable reflectarray (RA) antenna compared to conventional RA. Two innovative ways of realizing mechanically reconfigurable RA antenna is proposed: electromagnets-controlled RA and rotatable cylinder RA.For electromagnets-controlled RA, A novel mechanically reconfigurable RA element actuated by an electromagnet working in C-band is proposed. 1-Bit phase shift of reflecting wave is achieved by bending a half-wavelength dipole with magnetostatic force. For rotatable cylinder RA, a low-cost approach for the design of mechanically phase-tunable RA elements operating in the C-band is proposed. The proposed element composes of an open cylindrical shell made of a non-uniform dielectric material. A 2-bit phase tunability is achieved by implementing mechanical rotation of the open cylindrical shell.
