vivaldiAntipodal
Description
The vivaldiAntipodal
object creates an antipodal Vivaldi
element. Antipodal Vivaldi come under the group of end-fire tapered slot antennas, and such
antennas are expected to provide medium gain with less side lobes and wide bandwidth. These
antennas are low cost, geometrically simple in shape, and mostly used in wireless
communications and radar applications.
Creation
Description
creates an antipodal
Vivaldi object. By default, the antenna is centered at the origin and the dimension are
chosen for an operating frequency of 3.22 GHz.ant
= vivaldiAntipodal
sets
properties using one or more name-value pairs. For example, ant
= vivaldiAntipodal(Name,Value)aviv =
vivaldiAntipodal('BoardLength',0.2)
creates a antipodal Vivaldi with a board
length of 0.2 m.
Note
Properties you do not specify retain their default values.
