Abstract
The design, development and testing of an X-band 137 element passive reflect-array capable of incorporating active devices such as transistor amplifiers is presented. In order to avoid grating lobes in the radiation pattern, the inter-element spacing is minimised using dual-feed aperture coupled patch antenna elements. Far-field radiation pattern results are presented and compared with the predicted radiation patterns. Problems associated with phase errors, which contribute to the rise of sidelobes, are investigated
