monopoleCustom
Description
The monopoleCustom
object creates a monopole radiator of any
shape using the antenna.Shape
class. The ground plane can take any shape. You
can create any arbitrarily shaped monopole and analyze it for field, surface, and port
characteristics. Monopole antennas have a simple structure and provide omnidirectional
radiation patterns with wide impedance bandwidth. Monopole antennas are commonly used in
airborne and ground-based communication systems.
Creation
Description
creates a default
monopole antenna with a square radiator and a circular ground plane. The feed point is
at the origin in the xy- plane. The default antenna resonates at an
operating frequency of 1.24 GHz.ant

sets
Properties using one or more
name-value pairs. For example, ant
= monopoleCustom(Name,Value)ant =
monopoleCustom('RadiatorTilt',90)
creates a monopole antenna with tilt angle
of the radiator at 90 degrees on the z-axis.
