Abstract
For an optimum communication link,
antennas at both ends must share the same
polarization. Under certain conditions, the
polarization state of an electromagnetic wave
propagating in free-space may be rotated. As a
result, the transferred information may arrive
corrupted or lost. As satellite communication
systems migrate towards higher frequency bands
such as the Ka-band, depolarization, mainly due to
weather effects, becomes particularly relevant. In
this respect, circular polarization is more robust.
Here, a dual-band all dielectric polarization
converter which converts linearly polarized plane
waves into high purity circularly polarized waves is
proposed. Thanks to their metal-free nature, these
type of devices are able to withstand high powers,
such as those required for satellite communications.
