monopole
Create monopole antenna over rectangular ground plane
Description
The default monopole
object is a monopole antenna mounted
over a rectangular ground plane resonating around 72 MHz.
The width of the monopole is related to the diameter of an equivalent cylindrical monopole by the equation
, where:
d is the diameter of equivalent cylindrical monopole
r is the radius of equivalent cylindrical monopole.
For a given cylinder radius, use the cylinder2strip
utility function to calculate the equivalent width. The
default monopole is center-fed. The feed point coincides with the origin. The origin is
located on the xy- plane.
Creation
Description
creates a
quarter-wavelength monopole antenna with default dimensions. The default
dimensions are chosen for an operating frequency of around 72 MHz.mpl
= monopole
sets properties using one or more
name–value arguments. mpl
= monopole(PropertyName=Value
)PropertyName
is the property name
and Value
is the corresponding value. You can specify
several name-value arguments in any order as
PropertyName1=Value1,...,PropertyNameN=ValueN
.
Properties that you do not specify, retain their default values.
For example, m = monopole(Height=3)
creates a monopole
antenna of height 3 m.
