Abstract :
Beamforming is an integral part of modern wireless communication systems and a key component of beamforming is to have the ability to define specific nulls in the radiation pattern. Moreover, conformal antennas are being used in wireless systems to provide coverage in previously unavailable areas. This paper investigates the affects that a conformal surface may have on the specifically defined nulls associated with a desired beamformation. In particular, a 1×4 conformal array on a wedge-shaped surface is evaluated and analytical computations are validated with measurements.
