Reflectarray antennas: A review - FERMAT
The design of patch with ground plane contain slots is termed as ground-cut slot technique [24] as shown in figure 8. Compared to the standard rectangular patch antenna, the patch antenna with slot at ground plane as shown in figure below, gives 62.3% reduction in area, having same resonant frequency. Phase-shifting cell loaded with variable capacitances for ... A new dual linearly polarized phase-shifting cell for reflectarray applications is presented. It consists of two orthogonal sets of parallel rectangular slots etched in a ground plane. Each set may be loaded with a combination of variable and fixed capacitances to provide a Annular Slot Loaded High-Impedance Ground Plane difference between the proposed ground plane and the conventional high impedance surface is the lack of periodicity in the structure, which greatly simplifies the manufacturing process. Section I explains the operation of the annular slot loaded high-impedance ground plane and its application to a low profile loop antenna.
