This contribution presents the design of an electronic controllable reflectarray element using ohmic MEMS as switching devices. The proposed element is based on two patches aperture-coupled to a microstrip network with a common delay line, forming a sub-array. The electric length of the line can be modified by the inclusion of a series switch between two segments of the microstrip line. The ohmic...
In this contribution different dual-linear polarization elements for reflectarrays are proposed with the aim of achieving more than one cycle of 360° of phase delay for both polarisations, with low cross-polarisation levels, enough room for adding control devices and a linear phase response in the two bands, one from 10.70 GHz to 12.75 GHz (Rx) and the other from 14.00 GHz to 14.50 GHz (Tx). The elements...
