dipoleCylindrical
Description
The dipoleCylindrical
object creates a center-fed cylindrical
dipole antenna resonating around 70 MHz. The length of the cylindrical dipole corresponds to
half of the wavelength at the operating frequency. These antennas are used in wireless
communication applications requiring thicker dipoles due to their simple
design.
Creation
Description
creates a center-fed
cylindrical dipole antenna with default property values. The default dimensions are
chosen for an operating frequency of around 70 MHz.ant
= dipoleCylindrical
sets properties
using one or more name-value arguments. ant
= dipoleCylindrical(Name=Value
)Name
is the property name and
Value
is the corresponding value. You can specify several
name-value arguments in any order as Name1=Value1,...,NameN=ValueN
.
Properties that you do not specify, retain their default values.
For example, ant = dipoleCylindrical(Radius=0.04)
creates a
cylindrical dipole antenna with radius of 0.04 meters.
