Broadband notch antenna
First Claim
1. An antenna structure for receiving or transmitting electromagnetic waves comprising a substrate having an outer surface, a first conducting radiator disposed on one side of the outer surface of said substrate and having a first curved edge, a second conducting radiator disposed on the other side of the outer surface 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 gap therebetween with adjacent curved edges gradually tapering outwardly therefrom to define first and second continuous flared notches interfacing one another and emanating from said feed-point gap.

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.

- 6. A nonresonant antenna having a radiation pattern and impedance characteristics that are essentially independent of frequency over a wide bandwith comprising a support substrate, a first metallization disposed on the surface of said substrate and having a first curved edge, a second metallization disposed on the substrate and having a second curved edge, said first and second curved edges being closely related to one another and spaced apart from a feed-point gap, the curved edges of each metallization gradually tapering outwardly from said gap to define a pair of continuous dual flared notches.
- 10. An antenna structure for receiving and transmitting electromagnetic waves comprising a substrate, an upper planar conducting antenna element on one side of the surface of said substrate and having a first curved edge, a lower planar conducting antenna element disposed on the adjacent side and having a second curved edge closely related to the first curved edge in close proximity and spaced apart from each other to define a feed-point gap at a point of closest proximity therebetween with each antenna element and its associated curved edge on different sides of the substrate, each curved edge gradually tapering outwardly from the gap to define first and second continuous flared notches.
