monopoleRadial
Description
The default monopoleRadial
object creates a monopole antenna
mounted on a radial ground plane resonating around 75 MHz. The monopole radial antenna is a
variant of the monopole antenna, where the antenna is mounted on radials as versus a
rectangular ground plane. These antennas are commonly used in airborne and ground-based radio
communications.
Creation
Description
creates a default quarter
wavelength monopole antenna with a radial ground plane. The default antenna object is
center-fed with the feed point located at the origin on the xy-plane.
The default dimensions are chosen for an operating frequency of around 75 MHz.mpr
= monopoleRadial
sets properties
using one or more name–value arguments. mpr
= monopoleRadial(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, monopoleRadial(Height=2.2)
creates a monopole
antenna mounted on a radial ground plane with height of 2.2 meters. You can specify
multiple name-value pairs. Enclose each property name in quotes. Properties not
specified retain their default values.
