Many wireless communication applications such as satellite communications use circularly
polarized (CP) signals, with the requirement for easy switching of the polarization sense …

In this work, first the necessary conditions for a versatile cross‐polarization conversion meta‐
atom that operates both for linear and circular cross polarizations are discussed. Based on …

Reflectarrays (RAs) offer low-cost and low-profile solutions for reflector antennas that are
polarization and frequency selective. These features augment their capabilities for point-to …

Planar transmit arrays (TAs) have been an attractive solution as gain enhancers for various
applications, eg, satellite communications. The TA performance directly depends on its …

A wideband circularly polarized (CP) transmitarray antenna (TA) is presented for millimeter-
