Thermally tuned coaxial cable for microwave antennas

摘要

A coaxial cable, including an inner conductor and an outer conductor surrounding the inner conductor and a thermally responsive material positioned between the outer conductor and the inner conductor. The outer conductor is in a generally concentric relationship to the inner conductor and the inner and outer conductors are adapted to connect to an energy source. A thermal change in the thermally responsive material alters the generally concentric relationship between the outer conductor and the inner conductor.

1. A coaxial cable, comprising:
an inner conductor; an outer conductor surrounding the inner conductor, the inner conductor in general concentric alignment with the outer conductor, the inner and outer conductors adapted to each connect to an energy source; and a thermally responsive material disposed between the inner and outer conductors; wherein a change in temperature of the thermally responsive material alters the concentric alignment of the inner and outer conductors.
