Abstract :
A reflectarray antenna that provides a focused beam in Ka band has been designed, manufactured and tested. The antenna demonstrator has been made up using two layers of patches printed on Kapton, which are bonded to low-loss prepreg quartz materials. The effect of the manufacturing tolerance errors in the dimensions and dielectric properties of the materials have been evaluated. A good concordance is achieved between simulations and measurements after taking into account the deviation in dimensions and dielectric constant. The measured 18-cm antenna provides a gain better than 33 dB in a frequency band from 31 GHz to 34 GHz.
