Frequency reconfigurable antenna decoupling for wireless communication

A mobile device comprising:

• a first antenna port coupled to a first antenna element and configured to receive or transmit at a first resonant frequency based on the coupling of the first antenna port to the first antenna element;
• a second antenna port coupled to a second antenna element and configured to receive or transmit at a second resonant frequency based on the coupling of the second antenna port to the second antenna element, wherein the first antenna element and the second antenna element share a mutual coupling during frequency division duplex communication processing;
• a first parasitic scattering element, coupled to the first antenna port, configured to generate a plurality of coupling paths between a plurality of monopoles created by resonances of the first antenna element and the second antenna element in a dipole radiation mode of operation;
• and
• a second parasitic scattering element, coupled to the second antenna port, and configured to isolate a resonance of the second antenna element from the first antenna element.

A method adapted for frequency reconfigurable antenna decoupling used in a mobile communication device, the method comprising:

• operating a first monopole antenna element of a transmission path to generate a first radiation pattern;
• operating, concurrent to the first monopole antenna element, a second monopole antenna element of a reception path to generate a second radiation pattern that forms a mutual coupling with the first radiation pattern;
• and
• modifying a radiation pattern of the first monopole antenna element or the second monopole antenna element by generating an additional current path via a parasitic scattering element along a ground plane along with a current path coupling the first monopole antenna element and the second monopole antenna element.
