Reflect array Antenna based on Vertical polarized Square Patch Unit cell for Ku-Band Application

A single layer tiny reflect-array antenna is presented her based on square patch for Ku-band applications which operates at the frequency band from 10.7GHz to 11. 7GHz. Initially the microstrip patch unit cell element is designed for the center frequency of 11. 2GHz. Then, the phase optimization is done by varying the length of patch to obtain the linear phase range of 0° to 360°. A 11×11 reflectarray antenna is designed using a single layer microstrip array with the size of 165mm×165mm. The Computer Simulation Technology (CST) software is used for the simulation of the whole reflectarray antenna on the Taconic RF-35 substrate with dielectric constant 3.5. The designed reflectarray antenna is validated by analyzing 2-D and 3-D radiation pattern and gain.
