Investigations on Liquid Crystal Recon gurable Unit… Elements with Variable Slots in the Ground Plane. The etching of a slot in the ground plane under the microstrip patch has the effect of inductively loading the patch, since the path of26 2. Microstrip Reflectarrays. Through the slots, a small part of the power can leak and radiate toward the back of... Infrared Polarizing Reflectarray Metasurfaces Abstract— An infrared-frequency polarizing reflectarray is designed with a phase-amplitude synthesis method at 4µm wavelength. The proposed phase-amplitude synthesis method is based on the optimization of the axial ratio of the steered beam through the reflection phase and amplitude of...

Design and Analysis of Microstrip Reflectarray Antenna ... There are a few kinds of phase compensation methods available for the fixed-beam reflectarray such as using open-circuited stubs [4], variable patch size [5], slot-loaded ground plane [6], slot-loaded patch [7] and the usage of electronic components [8]. Stubs produce some dissipative losses as well as spurious radiation when it is being bent. (PDF) Phase range improvement of unit cell of reflectarray ... There are a few kinds of phase compensation methods available for the fixed-beam reflectarray such as using open-circuited stubs [5], variable patch size [6], slot-loaded ground plane [7], slot-loaded patch [8] and the usage of electronic components [9]. Reflectarray with slots of varying length on ground plane ...
wave have been introduced such as using elements with variable sizes, slots with variable lengths on the ground plane, and microstrip reflectarray with elements having variable rotation angles [10]. There are several designs for reflectarray and transmitarray using dipoles, microstrip patches, and dielectric resonator antennas which have
