Implementation of an Innovative Method to Design Reflectarray Antennas

, 2020
A novel computed aided technique for designing reflectarray antennas is presented. The developed approach automatically generates the geometrical model of reflectarray antennas taking into account some input parameters, such as, the unit cell type and ...

Three‐dimensional metal‐only phoenix cell and its application for reflectarrays

IET Microwaves, Antennas & Propagation
A 3D metal‐only waveguide‐based phoenix cell for reflectarray is presented. The proposed cell consists of two concentric square waveguides and a metallic block in the centre, which offers two operation modes. The first mode uses its cross section to tune

Comparison between an optical dielectric resonator nano-antenna reflectarray and an equivalent dielectric grating reflector

, 2013
Conventional metallic nanoantennas suffer significant energy dissipation introduced by Drude metals in the optical frequency range. To overcome this limitation, optical dielectric resonator antenna (DRA) was proposed and demonstrated through a ...

Multimode and Multiband Microstrip Antennas [PDF]

, 2007
This thesis describes original work on the broadband and multiband matching of microstrip patch antennas. Microstrip patch antennas suffer from many constraints on their performance. One major restriction is their narrow impedance bandwidth.
