ABSTRACT:
A coaxial cable antenna is provided for use in an external device, such as a programmer or monitor, to enhance communication between the external device and an implanted medical device (IMD). The coaxial cable antenna provides the external device with polarization diversity. For example, the coaxial cable antenna includes a first portion and a second portion that are substantially perpendicular to one another. Each of the portions of the coaxial cable antenna has a different polarization orientation, thus providing the programmer with polarization diversity. Further, the external device may include more than one coaxial cable antenna to provide the external device with spatial diversity as well as polarization diversity provided by the coaxial cable antenna design. The coaxial cable antenna configurations reduce problems associated with polarization mismatches, antenna nulls, and multi-path propagation interference.
