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...
This contribution presents the design of a dual linear polarized reflectarray element based on patches aperture-coupled to delay lines. The periodic element has been modified to allow dual polarization capabilities preserving its main advantages: a wide range of phase delay, linear phase response and low reflection losses. The linearity of the phase curve as a function of the length line has been...
Reflectarray antennas show a narrow bandwidth as a result of two factors: the narrow bandwidth of the radiating elements and the differential spatial phase delay. The last factor is specially important in large aperture reflect arrays. In this contribution, the bandwidth of reflect arrays is increased significantly by the inclusion of radiating elements with very linear response which allows true-time...
