Using Metal cylinder rod replace rectangle shape Yagi-uda antenna design

Hi I want to ask is there any ways to change the geometry shape of antenna toolbox designing yagi antenna. The default shape is in rectangle shape, and I want it to be in cylindrical form as I want to create it physically. Is there any ways to change the shape?

Hi Lee,

While the default shape is rectangular, but the parameters are equivalent to the cylindrical which are calculated from the following function. you can use the same and proceed for the design of Yagi Uda antenna, the resultant radiation pattern is equivalent to the one that you're aiming for irrespective of the shape.

The exciter, reflector, and directors have equal widths and are related to the diameter of an equivalent cylindrical structure by the equation:

w=2d=4r

The "cylinder2strip" function can be helpful for approximating cylindrical elements with rectangular ones in your Yagi-Uda design.

Provide the radius of the cylindrical elements you want to use to proceed. Ref: https://www.mathworks.com/help/antenna/ref/cylinder2strip.html, you can also refer to the following example for understanding the Yagi-Uda Antenna design using dipole strips: https://www.mathworks.com/help/antenna/ug/design-optimization-of-a-six-element-yagi-uda-antenna-surrogate-method.html?searchHighlight=yagi%20uda%20cylindrical&s_tid=srchtitle_support_results_2_yagi%20uda%20cylindrical
