monopoleCylindrical
Description
The monopoleCylindrical
object is a cylindrical monopole
antenna mounted over a rectangular ground plane. This antenna is useful for designing thicker
monopole antennas. These antennas are mostly used in wireless mobile communication due to
their broadband characteristics and simple design.
Creation
Description
creates a
cylindrical monopole antenna object with default dimensions for an operating frequency
of 70 MHz.ant

sets
Properties using one or more
name-value pairs. For example, ant
= monopoleCylindrical(Name,Value)ant =
monopoleCylindrical('Radius',0.04)
, creates a cylindrical monopole antenna
with a radius of 0.04 meters.
