draRectangular
Description
The draRectangular
object creates a rectangular dielectric
resonator antenna. The rectangular dielectric resonator antenna consists of a
rectangular-shaped dielectric placed on a ground plane. It has high power-handling capacity
and can provide high gain and bandwidth. The rectangular dielectric resonator antenna has the
advantage of two aspect ratio that aids in the generation of various modes. These antennas are
more suitable for use at microwave frequencies. Rectangular dielectric resonator antennas are
widely used in satellite and radar systems.
Creation
Description
creates a rectangular
dielectric resonator antenna with dimensions for a resonant frequency of 3.3 GHz. The
default antenna is probe fed with the feed point at the origin.ant
= draRectangular
creates a
rectangular dielectric resonator antenna with additional Properties specified using one
or more name-value arguments. ant
= draRectangular(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, draRectangular(ResonatorLength=0.04)
creates a
rectangular dielectric resonator antenna with the length of the dielectric resonator set
to 40 mm.
