Comparison of different structures for transmitarray cells

This paper presents the comparison between two different transmitarray cells, one based on stacked slots and the other on aperture coupled patches. Both structures can achieve a phase shift of up to 360° keeping a reasonable level of transmission. Since the patches cell showed more stability with the incident angle, it was chosen to be fabricated and measured in a waveguide simulator. © 2013 Wiley Periodicals, Inc.
