Abstract:
A method of structuring an antenna, comprising the steps of:providing a first dielectric antenna rod having a first dielectric constant, the first dielectric antenna rod being coupled to a first frequency transmission source for propagating first frequency band radiation from the first dielectric antenna rod into a medium having a medium dielectric constant; and coaxially mounting the first dielectric antenna rod within a second dielectric antenna rod having a second dielectric constant, the second dielectric antenna rod being coupled to a second frequency transmission source for propagating second frequency band radiation from the second dielectric antenna rod into the medium; wherein the first dielectric constant is greater than the second dielectric constant and the second dielectric constant is greater than the medium dielectric constant, and wherein the difference between the first dielectric constant and the second dielectric constant is greater than about 10.
