A concept of building a low cost integrated AESA has been investigated. A C-band active array antenna board has been designed, built and tested. A printed circuit board with active receiving circuits and antenna feed is mounted on an aluminum plate including the antenna elements. Measurements of the C-board antenna agree well with the simulated results. A bandwidth of about 20% with a return loss better than -10 dB when scanned to 45deg, a gain of 18 dBi and a side lobe level of 18 dB was obtained.
