Laboratory work # 2 Theme: Design and analyze wireless antennas using the Antenna Designer application Purpose

Plot Current Distribution, 3-D, Azimuth, and Elevation Patterns

In the SCALAR FREQUENCY ANALYSIS section of the toolstrip, click Current to view the current distribution of the helix at 1.8 GHz.

Click 3D Pattern, AZ Pattern, and EL Pattern to view the radiation, azimuth, and elevation patterns of the helix antenna, respectively. Click Tile again to view all the plots together.

You can compare the results of this tutorial with the results of Antenna Modeling and Analysis tutorial: Antenna Modeling and Analysis

Export to MATLAB Workspace

Click the Export button arrow and then click Export tto workspace. In the Export to workspace window, type the name of the antenna file. Click on the variable in the workspace to view the properties of the helix antenna.

Export to MATLAB Script

Click the Export button arrow again and then click Export to script to view the helix antenna and analysis in MATLAB script format. The script has two sections: Antenna Properties and Antenna Analysis.



Laboratory work # 3
Theme: Design and analyze dipole antennas using the Antenna Designer app
Purpose: Learn to work with the Matlab Simulink environment. Study the design principle and parameters of dipole antennas.

The dipole object is a strip dipole antenna on the Y-Z plane.

The width of the dipole is related to the diameter of an equivalent cylindrical dipole by the equation

w=2d=4r

where:

• 
  d is the diameter of equivalent cylindrical dipole.
  
• 
  r is the radius of equivalent cylindrical dipole.
  

For a given cylinder radius, use the cylinder2strip utility function to calculate the equivalent width. The default strip dipole is center-fed. The feed point coincides with the origin. The origin is located on the Y-Z plane.
