waveguideSlotted
Create slotted waveguide antenna
Description
The default waveguideSlotted
object creates a slotted waveguide
resonating around 2.4 GHz. There are different types of slotted waveguides, including
longitudinal slots, transversal slots, center inclined slots, inclined slots, and
inclined slots cut into a narrow wall. Slotted waveguide antennas are used in navigation
radar as an array fed by a waveguide.
Creation
Description
creates a
slotted waveguide on the xy- plane with default property
values. The default dimensions are chosen for an operating frequency of
around 2.4 GHz.ant
= waveguideSlotted
sets properties using one or more name–value arguments.
ant
= waveguideSlotted(PropertyName=Value
)PropertyName
is the property name and
Value
is the corresponding value. You can specify
several name-value arguments in any order as
PropertyName1=Value1,...,PropertyNameN=ValueN
.
Properties that you do not specify, retain their default values.
For example, ant = waveguideSlotted(Height=1)
creates a
slotted waveguide with a height of 1 meter.
