Planar Antenna (Mobile phone) - CST2013 MWS Examples

下载CST设计文件

General Description

This example shows the simulation of a Planar Antenna (PIFA) of a Mobile phone. The geometry of the antenna is imported by a CAD file. The simulation applies an AR-filter and uses a matching network in CST DESIGN STUDIO. S-parameters and farfields are calculated.

Structure Generation

The antenna is created by importing a CAD file for the geometry. Materials are assigned using the Material Library (Modeling: Materials Material Library Load from Library...). The boundary conditions are open (add space).

Solver Setup

For the excitation a discrete port (50 Ohm) is defined; the frequency range is from 0 to 2.5 GHz. Field monitors are defined at 0.9 and 1.8 GHz. The T-solver with an AR-filter is applied. The AR-filter is a linear predictor which is used to approximate the time signals. The resulting S-Parameters are independent from truncation errors. The AR filter can be employed online during the simulation (T-solver specials).

Post Processing

The scattering parameters and the time signals can be accessed through the 1D Results folder in the navigation tree. The farfield can be found in Farfields. A matching network is afterwards in CST DESIGN STUDIO applied to get the matched fields.

These three-dimensional field results can be displayed in CST MICROWAVE STUDIO:
