Synthesis of broadside uniform circular antenna array with low on-surface scanning

Circular Array is one of the most widely used antenna array designs. Its applications include radio direction finding, air and space navigation, underground propagation, radar, sonar, and many other applications. A broadside uniform circular array radiates (receives) not only in the broadside direction, but, in the other directions as well. Such an array has a significant power loss due to along resting plane scanning property. The power radiation or reception pattern of a circular array is dependent on the linear distance between two consecutive elements, the radius, and the number of elements. This paper aims to reduce the along resting plane scanning by adjusting the uniform inter-element distance and the radius of the array. It has been shown analytically that, with proper choice of number of elements, and radius, the on-resting plane scanning of the array can be minimized significantly.
