reflectorSpherical
Description
The reflectorSpherical
antenna object creates a spherical
reflector-backed antenna. The reflector in the spherical reflector-backed antenna is one-half
the size of the sphere. The antenna is used in wide-angle scanning on account of its perfectly
symmetrical geometric configuration.
Creation
Description
creates a
spherical reflector-backed antenna. The default antenna object has an exciter as a
center-fed dipole located on the X-Y plane. The default antenna object dimensions are
chosen for an operating frequency of 1 GHz.ant
= reflectorSpherical
creates a cavity-backed antenna, with additional Properties specified by one or
more name–value arguments. ant
= reflectorSpherical(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 not specified retain
their default values.
For example, reflectorSpherical(Radius=0.6)
sets the spherical
reflector radius to 0.6 meters.
