Antenna Design Architecture. The geometry of the proposed wide-slot defected ground structure antenna is portrayed in Figure 1.The antenna consists of simple wide square slot in the centre of one side of the substrate and fed line is printed on the other side for exciting two modes with close resonance frequency.
Slot length, specified as a scalar in meters.
Example: 'Length',2
Data Types: double
Slot width, specified a scalar in meters.
Example: 'Width',0.02
Data Types: double
SlotCenter — Slot antenna center
[0 0 0] (default) | three-element vector in Cartesian coordinates
Slot antenna center, specified as a three-element vector in Cartesian coordinates.
Example: 'SlotCenter',[8 0 0]
Data Types: double
GroundPlaneLength — Ground plane length
1.5000 (default) | scalar
Ground plane length, specified as a scalar in meters. By default, the length is measured along the x-axis.
Example: 'GroundPlaneLength',3
Data Types: double
GroundPlaneWidth — Ground plane width
1.5000 (default) | scalar
Ground plane width, specified as a scalar in meters. By default, the width is measured along the y-axis.
Example: 'GroundPlaneWidth',4
Data Types: double
FeedOffset — Distance from center along x-axis
0 (default) | scalar
Distance from center along x-axis, specified as a scalar in meters. Offset from slot center is measured along the length.
Example: 'FeedOffset',3
Data Types: double
Load — Lumped elements
[1x1 LumpedElement] (default) | lumped element object handle
Lumped elements added to the antenna feed, specified as a lumped element object handle. For more information, see lumpedElement.
Example: 'Load',lumpedelement. lumpedelement is the object handle for the load created using lumpedElement.
Example: s.Load = lumpedElement('Impedance',75)
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.
Antenna Ground Plane Design
Example: 'Tilt',90
Example: 'Tilt',[90 90],'TiltAxis',[0 1 0;0 1 1] tilts the antenna at 90 degree about two axes, defined by vectors.
Data Types: double
Ground Plane Antennas
TiltAxis — Tilt axis of antenna
[1 0 0] (default) | three-element vector of Cartesian coordinates | two three-element vectors of Cartesian coordinates | 'X' | 'Y' | 'Z'
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'.
For more information, see Rotate Antennas and Arrays.
Example: 'TiltAxis',[0 1 0]
2 Meter Ground Plane Antenna
Example: 'TiltAxis',[0 0 0;0 1 0]
