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.
Claims15
A method of transmitting and receiving signals using a cross polarized antenna system, comprising:
- (a) providing at least a first ultra-wideband (UWB) antenna radiating a first E field and a first H field;
- (b) providing at least a second ultra-wideband (UWB) antenna radiating a second E field and a second H field;
- (c) positioning said first UWB antenna substantially close to said second UWB antenna;
- and
- (d) creating a cross polarized field pattern, wherein said first E field and said first H field are substantially orthogonal to said second E field and said second H field.
