lpda
Create printed log-periodic dipole array antenna
Description
Use the lpda
object to create a printed log-periodic dipole
array antenna. The default antenna is centered at the origin and uses an FR4 substrate.
This antenna is widely used in communication and radar due to advantages such as
wideband, high gain, and high directivity.
Creation
Description
lpdipole = lpda
creates a printed log-periodic dipole
array antenna using default property values.
lpdipole = lpda(Name,Value)
sets properties using one
or more name-value pairs. For example, lpdipole =
lpda('BoardLength',0.2)
creates a printed log-periodic dipole
array with a board length of 0.2 m.
Note
Properties which are not specified retain their default values.
