Abstract
The subject invention relates to an antenna having broadband characteristics. The antenna is a dual notch device capable of receiving or transmitting electromagnetic waves comprising a substrate, an upper planer conducting antenna element disposed on one side of the surface of said substrate and having a first curved edge, a second conducting antenna element disposed on the other side of said substrate and having a second curved edge, said first and second curved edges being closely related to one another and spaced apart in close proximity at one point to define a feed-point therebetween with adjacent curved edges gradually tapering outwardly therefrom to define flared notches interfacing one another and interconnected by said gap.
