Abstract :
Radiation efficiency of twin slots fed by coplanar waveguide on a conductor-backed two-layer substrate with high-low dielectric permittivities is investigated. It is shown that radiation efficiency can be significantly increased compared to the radiation efficiency of a single slot when the slots are appropriately spaced. Radiating slot feed lines are explicitly accounted for.
