✦ Synopsis


capacitances of slab lines with offset cylindrical bars. The results obtained in the case of three fundamental offset structures represent the capacitances of a slab line family with offset cylindrical bars. An extensive computation has been made. These data not only permit the exact design of various offset configurations of slab lines, but also provide a known accuracy for manufacturing various coaxial configurations of slab lines.

## Abstract This paper presents a new approach to the realization of dual‐band operation in a single printed‐dipole antenna by incorporating compact resonant cell (CRC) structures. A dual‐band antenna that operates at 900 MHz and 2.4 GHz is constructed to illustrate the design methodology. The over
