Slot Antenna Finite Ground Plane

Slot length, specified as a scalar in meters.

The slots on the patch or on the ground plane will help to design a antenna with improved bandwidth and effeciency. Key words: microstrip patch antenna, slots, bandwidth, gain, efficiency. 1.INTRODUCTION Microstrip slot antennas invented in 1938 by Alan Blumlein. Slot radiator or slot antennas are antenna that are. Finite slotted ground plane. Final antenna geometry i.e. With ‘I’ slot on dielectric plane and three horizontal slots on the ground plane, shows better improvement in the radiation characteristics. It can be clearly seen that impedance matching is dependent upon the micro-strip length. Varying the length.

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

LoadLumped 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.

Ground Plane Antennas

Example: 'Load',lumpedelement. lumpedelement is the object handle for the load created using lumpedElement.

Example: s.Load = lumpedElement('Impedance',75)

Ground Plane Antenna Calculator

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.

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

TiltAxisTilt 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'.
