A low-profile K-band phased array for airborne platform

This paper presents a 36-element K-band T/R phased array with height only 12.3mm. With only 36 elements in this array, the array can scan to ±50° in both H-plane and E-plane. Furthermore, by applying GaAs MMIC, the measured EIRP and G/T of the array are 51 dBm and G/T -12.5 dB/K respectively. The array with low-profile, small aperture and high performance is ideal for compact airborne platform applications such as unmanned aerial vehicles.
