ABSTRACT: Naturally suited array geometry for 360°coverage is the uniform circular array (UCA). A
comparison of two types of uniform circular array configurations is presented
in this paper. Due to its symmetrical geometry UCA is always targeted which
results in minimal change inside lobe levels and beam width when scanned by a
phased array antenna. Particle Swarm Optimization and Cuckoo algorithm are used
for the calculation of complex weights of the array elements. Comparisons are
drawn in the context of adaptive beam forming capabilities. Obtained results
suggest that planar uniform circular array (9:10) using Cuckoo algorithm, has
better beam forming properties with also reduced side lobe levels when compared
to other geometry.
