Antenna polarization separation to provide signal isolation
First Claim
Patent Images
1. An apparatus comprising:
- a first antenna component disposed substantially entirely in a first plane, said first antenna component radiating energy of a first polarization from said first plane; and
a second antenna component disposed substantially entirely in a second plane, said second antenna component radiating energy from said second plane in a second polarization distinct from the first polarization to provide a signal isolation between the first antenna component and the second antenna component, said first antenna component and said second antenna component coupled in close proximity in a single form factor, wherein the signal isolation comprises isolation between a first signal received in the first polarization and a second signal simultaneously transmitted in the second polarization, wherein the first signal and the second signal use a single frequency in common.

Abstract
A first antenna component has a first polarization. A second antenna component has a second polarization. The second polarization is distinct from the first polarization to provide signal isolation between the first antenna component and the second antenna component. The first antenna component and the second antenna component are coupled in close proximity in a single form factor.
