Abstract :
The scanning characteristics of a linear five-element antenna array on a wedge-shaped conformal surface is investigated in this work. In particular, the half-power beamwidth (HPBW) of a self-adapting array is studied for various changing conformal surfaces. A general array factor expression is derived and used to compute the HPBW. From these results, the self-adapting limitations of the array are outlined. Finally, analytical computations are validated with measurements.
