Investigation of Complexity-Constrained Peformance of Planar REConfigurable APerture Antennas (RECAPs)
Source: Jacobs University Bremen
A REConfigurable APerture (RECAP) antenna is a regular array of reconfigurable elements whose state can be changed dynamically. RECAPs have shown the potential to support many antenna operations (beamsteering, interference suppression, frequency agility, matching etc.) in a single aperture, but the level to which increasing complexity helps in achieving peak performance for a particular application has not been studied in detail. This paper investigates the beamsteering performance of a planar RECAP structure in terms of Number of Reconfigurable Ports (NRP) and number of possible states per port (NRS), demonstrating the dependence of RECAP performance on complexity.
