dipoleMeander
Create meander dipole antenna
Description
The dipoleMeander
class creates a meander dipole antenna
with four dipoles. The antenna is center fed and it is symmetric about its origin. The
first resonance of meander dipole antenna is at 200 MHz.
The width of the dipole is related to the diameter of an equivalent cylindrical dipole by the equation
, 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 xy- plane.
Creation
Description
creates a
meander dipole antenna with four dipoles.dm
= dipoleMeander
creates a meander dipole antenna with four dipoles, with additional
properties specified by one or more name-value pair arguments.
dm
= dipoleMeander(Name,Value)Name
is the property name and
Value
is the corresponding value. You can specify
several name-value pair arguments in any order as Name1

NameN
, ValueN
. Properties not
specified retain their default values.
