Title:
ELECTROMAGNETIC ANTENNA APPARATUS
Document Type and Number:
WIPO Patent Application WO2002027864
Kind Code:
A3
Abstract:
An apparatus for transfering electromagnetic energy intermediate a host device and a medium or free space adjacent to the apparatus in an impulse radio system includes: (a) an energy guiding means for guiding means is connected with the host device; (b) an electromagnetic energy channeling structure effecting the transferring and including a plurality of gap interfaces; and (c) a transition means for coupling the energy guiding means with at least one gap interfaces; and (c) a transition means for coupling the energy guiding means with at least one gap interface fo the plurality of gap interfaces. The transition means conveys the electromagnetic energy intermediate the energy guiding means and the at least one gap interface. The at least one gap interface intersects the transition means in a substantially continuous curve in selected planes intersecting the gap interface and the transition means.
