patchMicrostripCircular
Create regular or AI-based probe-fed circular microstrip patch antenna
Description
Use the patchMicrostripCircular
object to create a
probe-fed circular microstrip patch antenna. By default, the patch is centered at the
origin with feed point along the radius and the ground plane on the
xy- plane at z = 0.
Circular microstrip antennas are used as low-profile antennas in airborne and spacecraft applications. These antennas also find use in portable wireless applications because they are lightweight, low cost, and easily manufacturable.
You can perform full-wave EM solver based analysis on the regular
patchMicrostripCircular
antenna or you can create a
patchMicrostripCircular
type AIAntenna
and explore
the design space to tune the antenna for your application using AI-based
analysis.
Creation
Description
circularpatch = patchMicrostripCircular
creates a
probe-fed circular microstrip patch antenna.
circularpatch = patchMicrostripCircular(Name=Value)
sets additional Properties using
one or more name-value arguments. Name
is the property
name and Value
is the corresponding value. You can
specify several name-value arguments in any order as
Name1=Value1
, ...
,
NameN=ValueN
. Properties that you do not specify
retain their default values.
For example, circularpatch =
patchMicrostripCircular(Radius=0.2)
creates a circular patch
of radius 0.2 m.
You can also create a
patchMicrostripCircular
antenna resonating at a desired frequency using thedesign
function.You can also create a
patchMicrostripCircular
antenna from a microstrip patch typeAIAntenna
object using theexportAntenna
function.A
patchMicrostripCircular
typeAIAntenna
has some common tunable properties with a regularpatchMicrostripCircular
antenna for AI-based analysis. Other properties of the regularpatchMicrostripCircular
antenna are retained as read-only in itsAIAntenna
equivalent. To find the upper and lower bounds of the tunable properties, usetunableRanges
