摘要：
Design of a K-band reflectarray antenna using 15 x 15 double square ring elements printed on a single substrate and backed by a ground plane separated by an air layer is proposed. The double square ring element supplies a 530 degrees dynamic range of the reflection phase variation, and the phasing curves are nearly linear. A prototype is manufactured and tested, and good agreements between simulation and measurement are demonstrated. The measured gain is about 23 dBi at the center frequency 24 GHz, and the 1-dB gain bandwidth is about 20%. (C) 2011 Wiley Periodicals, Inc.
