  Fluid Antenna Systems (FASs) have recently been proposed for enhancing the
performance of wireless communication. Previous antenna designs to meet the
requirements of FAS have been based on mechanically movable or liquid antennas
and therefore have limited reconfiguration speeds. In this paper, we propose a
design for a pixel-based reconfigurable antenna (PRA) that meets the
requirements of FAS and the required switching speed. It can provide 12 FAS
ports across 1/2 wavelength and consists of an E-slot patch antenna and an
upper reconfigurable pixel layer with 6 RF switches. Simulation and
experimental results from a prototype operating at 2.5 GHz demonstrate that the
design can meet the requirements of FAS including port correlation with matched
impedance.
