draCylindrical
Description
The draCylindrical
object creates a cylindrical dielectric
resonator antenna. The cylindrical dielectric resonator antenna consists of a cylindrical
dielectric placed on the ground plane. It has high power-handling capacity and can provide
high gain and bandwidth. These antennas are more suitable for use at microwave frequencies.
Cylindrical dielectric resonator antennas are widely used in medium- and long-range
communications.
Creation
Description
creates a cylindrical
dielectric resonator antenna with dimensions for a resonant frequency of 1.5 GHz. The
default antenna is probe fed with the feed point at the origin.ant
= draCylindrical
creates a
cylindrical dielectric resonator antenna with additional Properties specified using one
or more name-value arguments. ant
= draCylindrical(Name=Value)Name
is the property name and
Value
is the corresponding value. You can specify several
name-value pair arguments in any order as
Name1
=Value1
, ...
,
NameN
=ValueN
. Properties you do not specify
retains their default values.
For example, draCylindrical(ResonatorRadius=0.04)
creates a
cylindrical dielectric resonator antenna with the radius of the dielectric resonator set
to 40 mm.
