Abstract
An investigation on accurate analysis of microstrip reflectarrays
is presented. Sources of error in reflectarray
analysis are examined and solutions to these issues are
proposed. The focus is on two sources of error, namely
the determination of the equivalent currents to calculate
the radiation pattern, and the inaccurate mutual coupling
between array elements due to the lack of periodicity. To
serve as reference, two offset reflectarray antennas have
been designed, manufactured and measured at the DTUESA
Spherical Near-Field Antenna Test Facility. Comparisons
of simulated and measured data are presented
to verify and demonstrate the improved results using the
proposed solutions.
