As
for the simulation part, we will simulate the performance
of the phase shifter and include the multilayer
dielectric approach integrated with Ferroelectric
materials. The multilayer dielectric approach will
be examined for reduction in conductor losses while
maintaining practical input impedances. |
| • |
Prototypes
of the multilayer filled phase shifter to verify
the simulations results. These designs will be
fed by coax line and will involve dc bias stubs
for changing the dielectric constant of the Ferroelectric
material. Designs will be made at x-band for the
easy availability of the test and measurement equipment. |
| • |
Separate
prototypes will be constructed to test and optimize
the biasing of the Ferroelectric material. |
