dipoleCylindrical
Description
The dipoleCylindrical
object creates a cylindrical dipole
antenna. The length of the cylindrical dipole corresponds to half of the wavelength at the
operating frequency. These antennas are used in designing thicker dipole antennas. These
antennas are mostly used in wireless communications due to their simple design.
Creation
Description
creates a cylindrical
dipole antenna object with default dimensions for an operating frequency of 70 MHz. The
default dipole is center fed, with the feedpoint at the origin located on the
y-z plane.ant

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