摘要：
A novel microstrip unit cell element with a simple structure is presented for designing circularly polarized reflectarray that converts a linearly polarized incident field into a radiated circularly polarized field. The unit cell element consists of a circular patch with two orthogonal slots etched in it. A parametric study was carried out using CST Microwave Studio (Computer Simulation Technology, worldwide) on the unit cell element to evaluate the effect of the unit cell's salient parameters. This unit cell element was used to design and implement a prime focus array, which had 3-dB gain bandwidth and 3-dB axial-ratio bandwidth equal to 7.6 and 8.6%, respectively.
