Dual-Band Circularly Polarized Transmitarray Antenna for Satellite Communications at (20 to 30) GHz

Juan Ramon Mosig, Hamed Hasani, Joana Rita Alves dos Santos Silva, Maria Garcia Vigueras, Santiago Capdevila Cascante

A novel dual-band polarization-independent transmitarray is introduced in this paper for communication systems in Ka-band. Thanks to its unit-cell topology, the transmitarray antenna demonstrates almost complete independent performance at two design freque ...

Multi-band reflectarray antennas in Ku and THz frequency bands

Hamed Hasani

Printed reflectarrays are low-cost, low-profile high gain antennas demonstrating distinctive advantages over conventional parabolic reflectors and phased-arrays. The flat, low weight reflecting surface of a reflectarray makes it an attractive alternative w ...

Single-Layer Quad-Band Printed Reflectarray Antenna with Dual Linear Polarization

Anja Skrivervik, Julien Perruisseau-Carrier, Hamed Hasani

A novel single layer, dual linear polarized unit cell is introduced for a quad-band reflectarray antenna in the Ku-band centered around 12, 13, 14, and 15.5 GHz. The unit-cell design is such that the resultant reflectarray antenna can be considered as four ...
