Dual band (K and Ka) electronically scanning reflectarray with RF MEMS switches
is designed, implemented and measured. Unit cell of the reflect array is composed of
conductor backed split-ring elements. In order to steer the beam, the phase of the
incident circularly polarized wave is controlled by RF MEMS switches that modify
the angular orientation of split-rings individually. Reflectarray is designed using unit
cell approach with periodic boundary conditions. The antenna is fabricated by using
surface micromachining process developed in METU MEMS Center. Radiation
patterns of the antenna are measured and compared with the simulations. It has been
shown that the reflectarray is capable of beam switching to 35° / in Ka band, 24° / in K
band.
