This paper presents a novel reflectarray elements for linear-to-circular polarizer. Frequency properties of the proposed resonant elements provide almost linear phase curves with the same slop, while achieving the reflection phase range of 360°. The phase difference between the V-pol. and the H-pol. is about 90° more than the fractional bandwidth 10 %(cross polarization level <–15dB and axial ratio...
This paper proposes a reflectarray antenna consisting of arbitrarily-shaped conductor elements on a flat surface. Reflectarray antennas with specified elements have been developed as a high-gain antenna and they can be applied to design for millimeter-wave antennas [1], deployable antennas [2] and millimeter wave imaging system [3]. Reflectarray antenna transforms an incident spherical wave into a...
