Abstract
Planar reflectarray antennas behave similarly to parabolic dish antennas, but are flat in their construction. They work by having areas on the planar surface of different reflection phase, causing the signal to be reflected to a focal point. This is done today by making planar patch antennas with the required reflection phase. These antennas are typically used in aerospace. This paper specifically discusses a planar reflectarray antenna that was originally constructed in Millimeter Wave Circularly Polarized Fresnel Reflector for On-Board Radar on Rescue Helicopters by K. Mazouni. In this paper, the authors eight different shaped antennas to form the planar reflectarray. The typical planar reflectarray would use eight variations on the same patch to achieve the required performance. This paper recreated the results of the simulations of the unit cell patches.
