Create inverted Amos sector antenna
sectorInvertedAmos object to create an inverted
Amos sector antenna consisting of four dipole-like arms. The antenna is fed at the
origin of the dipole. The dipole arms are symmetric about the origin. The operating
frequency of the antenna is at 2.45 GHz wireless.
amossector = sectorInvertedAmos creates an inverted
Amos sector antenna with four dipole-like arms.
amossector = sectorInvertedAmos(Name,Value) sets
properties using one or more name-value pair. For example,
amossector = sectorInvertedAmos('ArmWidth',0.2)
creates an inverted Amos sector with a dipole width of 0.2 m. Enclose each
property name in quotes.
ArmLength— Individual dipole arm length
[0.0880 0.0710 0.0730 0.0650](default) | vector
Length of individual dipole arms, specified as a vector with each element unit in meters.
'ArmLength',[0.0980 0.0810 0.0830
amossector.ArmLength = [0.0980 0.0810 0.0830
ArmWidth— Dipole arm width
0.0040(default) | scalar
Width of dipole arms, specified as a scalar in meters.
amossector.ArmWidth = 0.0025
NotchLength— Notch length
0.0238(default) | scalar
Notch length, specified as a scalar in meters. For an inverted Amos sector antenna with seven stacked arms, six notches are generated. Notch length is measured along the length of the antennas.
amossector.NotchLength = 0.001
NotchWidth— Notch width
0.0170(default) | scalar
Notch width, specified as a scalar in meters. For an inverted Amos sector antenna with seven stacked arms, six notches are generated. Notch width is measured perpendicular to the length of the antenna.
amossector.NotchWidth = 0.00190
GroundPlaneLength— Ground plane length
Ground plane length, specified as a scalar in meters. By default, ground plane length is measured along x-axis.
GroundPlaneWidth— Ground plane width
Ground plane width, specified as a scalar in meters. By default, ground plane width is measured along y-axis.
Spacing— Distance between ground plane and antenna element
Distance between ground plane and antenna element, specified as a scalar in meters.
amossector.Spacing = 0.0355
Load— Lumped elements
Lumped elements added to the antenna feed, specified as a lumped element
object handle. You can add a load anywhere on the surface of the antenna. By
default, it is at the origin. For more information, see
lumpedelement is the object handle for the load
Tilt— Tilt angle of antenna
0(default) | scalar | vector
Tilt angle of the antenna, specified as a scalar or vector with each element unit in degrees. For more information, see Rotate Antennas and Arrays.
'TiltAxis',[0 1 0;0 1 1]
tilts the antenna at 90 degree about two axes, defined by vectors.
TiltAxis— Tilt axis of antenna
[1 0 0](default) | three-element vector of Cartesian coordinates | two three-element vectors of Cartesian coordinates |
Tilt axis of the antenna, specified as:
Three-element vectors of Cartesian coordinates in meters. In this case, each vector starts at the origin and lies along the specified points on the X-, Y-, and Z-axes.
Two points in space, each specified as three-element vectors of Cartesian coordinates. In this case, the antenna rotates around the line joining the two points in space.
A string input describing simple rotations around one of the principal axes, 'X', 'Y', or 'Z'.
