loopRectangular
Create rectangular loop antenna
Description
The loopRectangular
object is a rectangular loop antenna on
the xy- plane.
The thickness of the loop is related to the diameter of an equivalent cylinder loop by the equation
, where:
d is the diameter of equivalent cylindrical loop
r is the radius of equivalent cylindrical loop
For a given cylinder radius, use the cylinder2strip
utility function to calculate the equivalent width. The
default circular loop antenna is fed at the positive y-axis. The
point of the y-axis is the midpoint of the inner and outer perimeter
of the loop.
Creation
Description
creates a
rectangular loop antenna in the X-Y plane. By default, the dimensions are
chosen for the operating frequency 53 MHz.lr
= loopRectangular
creates a rectangular loop antenna, with additional properties specified by
one, or more name-value pair arguments. lr
= loopRectangular(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 not specified retains their
default values.
