Abstract: An electronic device having multiple antennas and capable of operating in a wireless communication system, where interference between the multiple antennas is minimized using a detuning circuit activated by one or more antennas and resulting in detuning of at least one of the antennas. Activation of the detuning circuit can be accomplished by positioning an antenna to complete the detuning circuit and thereby activate the detuning circuit.

Abstract: An electrically small radiator structure for radiating electromagnetic waves having an electrical size, k*a, with a value less than &pgr;/2 and above &pgr;/20,000 and configured to have at least a first and second magnetic, or electric, dipole element. Dipole elements are preferably oriented such that a source-associated standing energy value for the structure, or Wds(tR), is low, Radiative Q value preferably less than ⅓(k*a)3; and each of the elements, whether paired with respective electric dipole elements, is in electrical communication through a feed circuit to at least one power source. Further, a first dipole pair (or element) oriented orthogonally with respect to a second pair (or element) are in voltage phase-quadrature; the structure is operational at a frequency below 5 GHz; and dipole moments oriented such that the following is generally satisfied: a divergence of the Poynting vector of the pairs with respect to retarded time, namely ∇|tR·N, has a value less than 1.0.
