This paper presents a Ku-Band (10 - 15 GHz) 64- element phased array utilizing commercially available silicon beamforming chipsets. The phased array is able to scan $\pm 30^{\circ}$ in both azimuth and elevation with less than 15 dB of cross-polarization. It supports linear vertical and horizontal polarizations as well as both transmit and receive modes utilizing half duplex operation. The array has a size of $4.2^{\prime\prime} \mathrm{x}\ 5.5$” and consumes 12.8 W in receive and 16 W in transmit. This array is demonstrated utilizing ROHACELL foam as a spacer in order to improve bandwidth.
