“…In recent years, many articles have been devoted to the study of phased arrays [13,14,15,16,17,18,24]. Pattern synthesis and beamforming have also been studied by researchers extensively [19,21,22,23,25,26,27,28,29,30,31]. However, these methods have not investigated how to thin the phased array.…”

Thinning of phased only rectangular planar array can reduce the cost and simplify the radio front end of the array. Therefore, it is reasonable to develop the thinning pattern synthesis approach for phased only rectangular planar array. In this letter, a novel computational approach is presented to form the beam pattern and thin the phased only rectangular planar array. First, a new simple matrix equation based on two-dimensional Fourier transform (FT) is derived to calculate the antenna element excitations and the beam pattern. Then, the computational steps to obtain the antenna element excitations with uniform amplitudes are presented. In order to increase the attenuation of the side lobes, the target beam pattern with varied phases determined by a novel analytical formula is proposed. Two examples are used to demonstrate the advantages of the new method. The simulation results show that the new approach can synthesize the beam pattern well, and the new pattern synthesis method has good performance in thinning the phased only rectangular array.

“…However, these articles ignore optimization for cross-polarization component. In [4], the particle swarm optimization (PSO) method is applied to synthesize the elliptical and linear polarization patterns for dual-polarized array with shaped main lobe and low side lobe and crosspolarization level. In [5], an improved differential evolution algorithm is proposed to achieve lower side lobe levels and suppress the cross-polarization.…”

An iterative convex optimization (ICO) algorithm is proposed to solve pattern synthesis problem under the framework of dual-polarized conformal arrays in this paper. The subproblems of shaping main lobe, optimizing side lobe, and suppressing cross-polarization component are summarized as a joint optimization problem. To solve this problem, the nonconvex constraint about main lobe is rewritten as a convex constraint, which will bring error. And an auxiliary phase function is introduced to correct this error alternatively. Due to the deviation between auxiliary phase and real phase of pattern function, a method minimizing the peak of the synthesis error over observation angles is effectively applied to further improve the performance of the method. Numerical examples show good pattern synthesis ability and convergence performance of the ICO method.

“…Although there are not many papers talking about this issue, few methods can be still found in the literature. They include, for example, polarization-controllable pattern synthesis for vector antenna arrays in [20], polarized focused and shaped pattern synthesis for arbitrary antenna arrays in [21]- [23], frequency-invariant polarized pattern synthesis for wideband conformal arrays [24], and circular-polarization (CP) pattern synthesis for spherical arrays [25]. However, all these research assumed a fixed desired polarization state for all angular space of interest.…”

This paper extends the semidefinite relaxation (SDR) method to be capable of synthesizing linearly polarized shaped patterns with accurate control of sidelobe level (SLL), cross-polarization level (XPL), and dynamic range ratio (DRR) of the excitation distribution for arbitrary antenna arrays. In addition, by using the vectorial active element patterns, mutual coupling and platform effect can be also incorporated into the proposed vectorial shaped pattern synthesis. Three examples for synthesizing linearly polarized patterns with different pattern shape requirements and different antenna array geometries have been conducted to check the effectiveness and robustness of the proposed method. Compared to the original vectorial shaped pattern synthesis without DRR control, the proposed method with the DRR control can significantly reduce the obtained DRR which is very useful in many antenna array applications. INDEX TERMS Vectorial shaped pattern synthesis, semidefinite relaxation (SDR), cross-polarization level (XPL), dynamic range ratio (DRR), mutual coupling.
