Abstract:
From the current distribution on planar monopoles,
transmission line modeling is applied to study this kind of antennas.
Some reported techniques for broadband monopoles are
approached by using this model from a qualitatively point of view.
Conclusions are derived that help to match the monopoles over an
ultrawide bandwidth regardless of whether they are folded or not.
Folded configurations are obtained in order to provide solutions
to specific designs and improve radiation pattern maintaining
the planar monopole broadband behavior. Three compact folded
prototypes with greater than 1:38 bandwidth are implemented
and tested. Pulse distortion is also discussed for this type of
applications.
