Directive multiple beams from linear-to-circular polarized reflectarray antenna

Alexandria Engineering Journal
We demonstrate the design of a highly directive circularly polarized planar reflectarray in this paper, with efficient polarization conversion from the linearly polarized excitation to the circularly polarized radiations based on a novel Jerusalem like ...

C-band Folded Reflectarray Antenna Using Integrated planar 2×2 Array Feed

, 2015
The horn antenna is usually used as the primary feeding source in the folded reflectarray antennas. By replacing the classical horn feed with an alternative planar 2×2 array source, a C-band folded reflectarray is realized and presented in this paper ...

Pattern matching by optimizing load in a reflectarray antenna

, 2009
A novel method to match radiation pattern of a reflectarray antenna by optimizing the load is presented in this paper. By varying the load attached to each element in a reflectarray the reflection coefficient at each element is varied, which varies the ...
