Reconfigurable Reflectarray Antenna

An X-band linearly polarized microstrip reconfigurable reflectarray antenna with beam steerable angle upto 16° has been designed, fabricated and measured. The unit cell consists of a microstrip patch on the top layer and variable length slot in the ground plane. The designed unit cell of dimensions 15mm x 15mm provides a reflection phase range of 153°. The array has 64 elements of different reflection coefficient phases in the form of a planar array. A reflectarray prototype has been measured in a far-field anechoic chamber facility at NUST, giving a gain of 14dB and axial ratio20dB at the operating frequency of 10GHz.
