Near-Optimal Shaped Beam Synthesis of Real and Coupled Antenna Arrays via 3D-FEM and Phase Retrieval.

Synthesizing Shaped Power Patterns for Linear and Planar Antenna Arrays Including Mutual Coupling by Refined Joint Rotation/Phase Optimization

“…This pattern has a circular flat- 4 (a) of [9]. For the proposed method, the same size of a planar array is used and a cavity-backed patch antenna presented in [38] is adopted as the array element. Suppose the user-desired polarization direction is still p d = e y .…”

A mm-Wave Patch Antenna with Broad Bandwidth and a Wide Angular Range

“…This will result in a flat pattern if 𝐹 (𝜗) is chosen as the inverse of the single element radiation characteristic 𝐶 (𝜗). This approach assumes real valued patterns 𝐹 (𝜗) and 𝐶 (𝜗), as opposed to more sophisticated beam synthesis methods taking also the phase of the radiated fields into account [38]. The method is applied for a simple radiation characteristic 𝐶 (𝜗) = sin 𝜗 for 𝑀 = 1 and 𝑀 = 4 in Fig.…”

Simultaneous Use of Addition Theorems for Cylindrical and Spherical Waves for the Fast Full-Wave Analysis of SIW-Based Antenna Arrays

“…On the other hand, a generalized scattering matrix (GSM) analysis based on the addition theorems for spherical waves and FEM, suitable for the fast analysis of finite arrays on a ground plane, was introduced in [13]. Since then, it has been successfully applied to different array problems such as the design of the Galileo system navigation antenna [14], multi-objective optimization [15], shaped beam problems [16], [17], or, recently, in the synthesis of nonuniform arrays [18] or arrays of rotated elements [19].…”
