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.
