In this paper a unit cell (of a micro strip reflect array antenna) consists of double circular ring element is proposed with enhanced bandwidth and linear reflection phase range. The micro strip reflect array unit cell operates in X Band (8-12 GHz) at the centre frequency of 10 GHz. The design proposed in this paper has a linear reflection phase range which enhances the pattern bandwidth of a micro strip reflect array unit cell. An soft HFSS software is used to carry out a parametric study to confirm the performance of the unit cell. Reflection phase range value of more than 550 degree and a phase slope value of 79 mm at the centre frequency of 10 GHz has been obtained with this unit cell. A pattern bandwidth of up to 24% on frequency band of 8.75 GHz to 11.14 GHz is achieved.
