“…In contrast with linear arrays using CORPS where the window of visibility is small with decreasing behavior in terms of side lobe level and directivity at the edges of the array. Moreover, in comparison with a planar antenna array with a CORPS-BFN, we can reach a simplification almost equal that the presented in [4] with M = N /2 input ports for the multi-beam configuration or lower with M = N /3 input ports for the mono-beam configuration. Furthermore, although this research work was intended as a theoretical contribution from simulations, depending on the design requirements for a particular application a proposed configuration can be easily implemented as previously mentioned.…”

“…We have set the parameters based on literature and our previous experience solving antenna problems. [4,8,9,12] The parameters of the DE algorithm were set as follows: the algorithm is executed using N p = 500 individuals (population size) through 1000 iterations to ensure a good sampling of the solution space, with a crossover probability C R = 1.0 and a mutation factor set in F = 0.5. A scheme with random selection, one difference vector and binomial crossover was implemented.…”

“…However, recent research work with CORPS-BFN has been focused in the feeding network for specific applications, [2] the development of new BFN designs to improve efficiency, [3] and the simplification of the network tackled in [4,5].

This research work deals with a innovative way to simplify the design of beam-forming networks (BFNs) for multi-beam steerable concentric ring arrays based on coherently radiating periodic structures (CORPS) technology. Mono-and multi-beam design configurations of CORPS-BFN for steerable concentric ring arrays are proposed and analyzed. The complex inputs of the feeding network for these configurations are optimized with the differential evolution algorithm. Simulation results reveal a significant simplification of the feeding network based on CORPS for concentric ring arrays reducing drastically the number of input ports to control each beam in both configurations analyzed.

“…These arrays have been widely used in applications, such as multi-functional radars and communication systems [1]. Many practical methods have been introduced in the past to produce a reconfigurable aperture with multiple patterns, including multi-mode feeding technologies for reflector antennas [2], and some multi-beam forming networks for antenna arrays [3][4][5][6]. Other studies focus on the design of phasedifferentiated antenna arrays using some sophisticated synthesis methods, such as alternating projection approaches [7,8], stochastic optimization algorithms [9][10][11], and some other techniques [12,13].…”

Abstract-It is shown in this paper that the problem of reducing the number of elements for multiplepattern arrays can be solved by a sequence of reweighted 1 optimizations under multiple linear constraints. To do so, conjugate symmetric excitations are assumed so that the upper and lower bounds for each pattern can be formulated as linear inequality constraints. In addition, we introduce an auxiliary variable for each element to define the common upper bound of both the real and imaginary parts of multiple excitations for different patterns, so that only linear inequality constraints are required. The objective function minimizes the reweighted 1 -norm of these auxiliary variables for all elements. Thus, the proposed method can be efficiently implemented by the iterative linear programming. For multiple desired patterns, the proposed method can select the common elements with multiple set of optimized amplitudes and phases, consequently reducing the number of elements. The radiation characteristics for each pattern, such as the mainlobe shape, response ripple, sidelobe level and nulling region, can be accurately controlled. Several synthesis examples for linear array, rectangular/triangular-grid and randomly spaced planar arrays are presented to validate the effectiveness of the proposed method in the reduction of the number of elements.

This research paper deals with a innovative way to simplify the design of beam-forming networks (BFNs) for multibeam steerable antenna arrays based on coherently radiating periodic structures (CORPS) technology using the noniterative matrix pencil method (MPM). This design approach is based on the application of the MPM to linear arrays fed by CORPS-BFN configurations to further reduce the complexity of the beam-forming network. Two 2-beam design configurations of CORPS-BFN for a steerable linear array are analyzed and compared using this compressive method. Simulation results show the effectiveness and advantages of applying the MPM on BFNs based on CORPS exploiting the nonuniformity of the antenna elements. Furthermore, final results show that the integration of CORPS-BFN and MPM reduces the entire antenna system including the antenna array and the beam-forming network subsystem resulting in a substantial simplification in such systems.
