Summary:
In this work, using a coplanar waveguide employing periodic ground structure (PGS) on silicon substrate, a highly miniaturized impedance transformer was developed for application to wide band communication system. Concretely, the multi-section transformer was designed using Chebyshev polynomials design technique for ultra broadband operation. Its size was 0.026 m2 on silicon substrate, which was 8.7 % of the one fabricated by conventional coplanar waveguide on silicon substrate. The impedance transformer showed a good RF performance over ultra broadband from 8 ? 49.5 GHz.
