Abstract
In this paper, a folded reflectarray antenna operating at Ka band is presented. A crossed-dipole element, which is able to provide a tuning phase range of more than 420° is used to construct the reflectarray. Simulations and experiments are conducted to validate the design. With the overall size of 210 mm × 210 mm × 45.5 mm, a peak gain of 27.3 dBi and a 3 dB-gain bandwidth of 27.7–31 GHz have been achieved in measurements. Sidelobe levels are less than −20.5 dB and −18.5 dB in the E and H planes, respectively.
