“…In recent years, there is growing interest of using 4D antenna arrays to synthesize the satellite footprint patterns (Chou et al, 2004;Villegas, 2007;Brégains et al, 2002;Yang et al, 2013;Chen et al, 2008;Zheng et al, 2010;Fondevila et al, 2004). In these proposed synthesis methods, the RPLs and DRR can be well decreased.…”

An efficient approach based on the combination of two-dimensional Woodward-Lawson analytical method and differential evolution optimization algorithm is developed for the synthesis of irregularly shaped radiation patterns based on four-dimensional planar arrays. Owing to the time-modulation of four-dimensional arrays, the ripples in the coverage area and the side-lobe levels are suppressed effectively. By combining the two-dimensional Woodward-Lawson method and differential evolution algorithm, the optimized time sequences and element excitations can be obtained. Radiation efficiency of time-modulated planar arrays also has been optimized and a significant improvement is achieved. Considering a practical application scenario where six-bit phase shifters are employed, the peak side-lobes have been suppressed significantly by employing the genetic algorithm. Numerical examples are presented to demonstrate the effectiveness and flexibility of the proposed approach.

“…In this context, it is desirable for a single antenna to be able to generate multiple radiation patterns, with the excitation corresponding to each being selectable by suitable switching devices [12]. Multibeam antennas can be considered as effective approach to perform independent data streams between a transmitter and a receiver.…”

Abstract-In this paper, we propose a multi-beam model for antenna array pattern synthesis (AAPS) problem. The model uses a conic trust region algorithm (CTRA) similarly proposed in this paper to optimize its cost function. Undoubtedly, whole algorithm efficiency ultimately lies on the CTRA, thereof, we propose a method to improve the iterative algorithm's efficiency. Unlike traditional trust region methods that resolve sub-problems, the CTRA efficiently searches a region via solving a inequation, by which it identifies new iteration points when a trial step is rejected. Thus, the proposed algorithm improves computational efficiency. Moreover, the CTRA has strong convergence properties with the local superlinear and quadratic convergence rate under mild conditions, and exhibits high efficiency and robustness. Finally, we apply the combinative algorithm to AAPS. Numerical results show that the method is highly robust, and computer simulations indicate that the algorithm excellently performs AAPS problem.
