hornPotter
Description
The hornPotter
object creates a Potter horn antenna. The Potter
horn antenna is a dual-mode, conical horn antenna with discontinuity. These antennas are used
in wireless applications where properties like low cross polarization level, low side lobe
level, and beam symmetry are required. Potter horns are widely used in satellite
communications for frequency reuse.
Creation
Description
creates a default Potter
horn antenna with tapered transition. The default dimensions are chosen for an operating
frequency of 3.8 GHz.ant
= hornPotter
sets Properties using one or more
name-value pairs. For example, ant
= hornPotter(Name,Value)hornPotter('ConeHeight',0.05)
creates
a Potter horn antenna with the cone height of 50 mm.
