Summary:
This paper presents design of a linearly polarized RL-MSAA. A stacked circular MSA is with different radii of upper and lower patches is introduced for the linearly polarized RL-MSAA. It is confirmed that radiation phase of the stacked MSA can be controlled by the radii of the circular patches in the range of around 180 degrees by simulation. A prototype RL-MSAA with three concentric rows of the stacked MSAs arranged at a spacing of 0.65 wavelengths is designed at 12 GHz. Uniform phase distribution and 22.3 dBi gain with 89% efficiency of the test RL-MSAA are measured at the design frequency. A validity of the stacked MSA with different radii for a linearly polarized RL-MSAA is demonstrated.
