Description
Summary:A new frequency selective reflectarray (FSR) comprising a crossed-dipole array and a frequency selective surface (FSS) of square loops printed on both sides of a dielectric substrate is presented for wireless communication applications. The reflectarray functions as a reflector, and generates the desired reflected beam shape while steering the primary wave source in the desired direction. Moreover, the FSR should be partially transparent for propagation channels of other communication systems working in other frequency bands. Some new FSR designs comprising 11 by 7 elements for dual-source and dual-polarized operation are given and verified by simulation and experiment. Furthermore, the FSR is applied to a WCDMA system to eliminate blind spots in communications between the base station and mobile users. A practical link budget analysis demonstrates the effectiveness of the FSR to improve the quality of communications. Finally, the proximity effect of concrete wall on the FSR is discussed to illustrate the applicability and flexibility of the proposed frequency selective reflectarray.
