1. A medical transceiver device for radio-based communication with an implantable medical device comprising;

  • circuitry for transmitting radio frequency signals to, and/or receiving radio frequency signals from, said implantable medical device, said radio frequency signals having a wavelength;

    first and second dipole antennas each having a structural length;

    an antenna feed network operatively interconnected between said circuitry and said first and second dipole antennas;

    each of said first and second dipole antennas being operable by said circuitry as a transmitting and/or receiving antenna for said radio frequency signals;

    said first and second dipole antennas being operable by said circuitry to emit and/or receive radio waves of different polarizations and thereby exhibiting polarization diversity; and

    said first and second dipole antennas being adjacent to each other at substantially a single location in space at a distance from each other of a size that is no larger than one-sixteenth of said wavelength, said size of said distance giving said first and second dipole antennas substantially no spatial diversity.
