Compound loop antenna system with isolation frequency agility
First Claim
1. An antenna system, the system comprising:
- a ground plane;
a first antenna coupled to the ground plane;
a second antenna coupled to the ground plane; and
a resonant isolator located between the first antenna and the second antenna, wherein the resonant isolator is coupled to the ground plane at or proximate to a first current null point created by the first antenna and at or proximate to a second current null point created by the second antenna, the first current null point and the second current null point each being an area on the ground plane where high current density occurs, and wherein the resonant isolator comprises at least two substantially parallel conductive portions and is configured to isolate the first antenna from the second antenna at a resonance.

Abstract
An antenna system is provided, including a first antenna, a second antenna, a ground plane, and a resonant isolator located proximate to the first antenna and the second antenna. The resonant isolator is coupled to the ground plane at or proximate to one current null point created by a first antenna and at or proximate to a second current null point created by a second antenna, and is configured to isolate the first antenna from the second antenna at a resonance. In some cases, the resonant isolator may include at least two conductive portions that may be substantially parallel to one another. The resonant isolator may also include an active tuning element that may change the resonance at which the resonant isolator de-couples the two antennas. In some cases, each of the antennas may be a capacitively-coupled compound loop antenna.
