Abstract:
The problem of pattern synthesis with cylindrical arrays is treated. A transformation that allows a circular array to be treated as a virtual linear array is presented. This transformation requires a large number of elements and it is used to synthesize patterns with narrow beams and low side lobes. Using cylindrical arrays, its directivity properties were enhanced and the main beam was steered in any direction in space. Another pattern synthesis approach requires that the pattern exhibits a desired distribution. A method that minimizes the squared error between the real and desired patterns for a given elevation for circular antenna arrays is introduced. It is extended to the case of cylindrical arrays where the error is minimized in the required plane, and the directivity is enhanced without the need to a very large number of elements.
