Abstract
An ultra-wideband magnetic antenna includes a planar conductor having a first and a second slot about an axis. The slots are substantially leaf-shaped having a varying width along the axis. The slots are interconnected along the axis. A cross polarized antenna system is comprised of an ultra-wideband magnetic antenna and an ultra-wideband dipole antenna. The magnetic antenna and the dipole antenna are positioned substantially close to each other and they create a cross polarized field pattern. The present invention provides isolation between a transmitter and a receiver in an ultra-wideband system. Additionally, the present invention allows isolation among radiating elements in an array antenna system.
Claims16
A method of isolating a plurality of ultra-wideband (UWB) antennas, comprising:
- (a) providing at least a first antenna of said plurality of UWB antennas having a null in a radiated field in a plane coincident with said first antenna;
- and
- (b) positioning at least a second antenna of said plurality of UWB antennas within said plane, wherein said positioning isolates said first antenna from said second antenna to prevent electromagnetic loading.
