Abstract-In this paper, a broadside circular array antenna resting on x-y plane is assumed. Design aim here is to obtain the optimal combination of non-uniform angular positions of the elements and uniform radius for the array, so as to acquire the radiation with the lowest possible sidelobe peak (SLL) with least possible first null beamwidth (BWFN) increment. Optimum angular locations of elements are found using Real coded Genetic Algorithm (RGA).

“…A radiation pattern with lowest SLL, more and deeper nulls, and, slenderer main beam is advantageous in the present case. RGA [30] is employed in this paper to obtain the desired pattern [7], [26], [30].…”

“…In this framework, aperture arrays of intermixed elements (often indicated as interleaved, interlaced or interspread arrays) provide interesting performances in terms of hardware complexity, aperture efficiency, and flexibility [1]. However, each array of an interleaved arrangement usually shows a lower gain and a higher peak sidelobe level (P SL) than the corresponding non-interlaced design [2].…”

“…More recently, stochastic optimization techniques [1] [2] or hybrid approaches [6] have been successfully applied. Despite their effectiveness, statistical methodologies are computationally inefficient when dealing with large apertures and a-priori estimates of the expected performances are usually not available.…”

This paper proposes an analytical technique based on Almost Difference Sets (ADSs) for the design of interleaved linear arrays with well-behaved and predictable radiation features.Thanks to the mathematical properties of ADSs, such a methodology allows the design of interlaced arrangements with peak sidelobe levels (P SLs) only dependent on the aperture size, the number of elements of each subarray, and the behavior of the autocorrelation function of the ADS at hand. P SL bounds are analytically derived and an extensive numerical validation is provided to assess the reliability, the computational efficiency, and the effectiveness of the proposed approach. It is worth noticing that, although without any optimization, such an analytic technique si still able to improve (on average 0.3 dB) the performances of GA-optimized layouts.

“…When considering global optimization methods for antenna designs, bio-inspired algorithms such as genetic algorithms (GA) [19] and Particle Swarm Optimization (PSO) [20,21], have been commonly used in the creation of design techniques that can satisfy constraints which would be otherwise unattainable.…”
