Another possibility expands the patch model to a set of four identical antennas, each excitable with its own coaxial feed. First, the farfield solution of the single patch antenna is applied to the antenna array feature, superimposing the results with different amplitudes and phase settings. In addition, the single patch antenna will be extended to a rectangular 2x2 array pattern using three different methods. The following explanations can be applied to other antennas as well.Īlthough, CST Microwave Studio can provide a wide variety of results, this tutorial will concentrate mainly on the S-parameters and farfield results. As a typical example you will analyze a circular patch antenna. In this tutorial you will learn how to simulate antenna devices. 163 Geometric Constructions Introduction and Model Dimensions Single Antenna (Frequency Domain Solver):Īntenna Array Combine (Transient Solver):Īntenna Array Simultaneous (Transient Solver): Please find the corresponding simulation models for this workflow example in the component library:
