【 摘 要 】

This paper deals with the design, fabrication and performance evaluation of a dual C slot compact reflectarray element. It has been demonstrated that the progressive phase distribution of array elements can be achieved by minor variation of C slot widths, without changing the entire patch dimensions. A comparison between measured and simulated results confirms wider phase range coverage of 340o and a 10% bandwidth of 70 MHz have been achieved. A good comparison between simulated and measured results has been exhibited by comparing three different slot widths of the proposed design.
