Dual frequency coplanar strip dipole antenna
The paper presents a novel coplanar waveguide (CPW) fed coplanar strip (CPS) dipole antenna which operates at dual frequencies. The transition from CPW to CPS is accomplished with the use of a wideband balun which exhibits less than 1 dB insertion loss up to 4.8 GHz. Return loss data for a single frequency CPS dipole is presented in addition to data showing the two resonant frequencies of the dual frequency CPS dipole antenna. The antenna patterns for both the single and dual frequency antennas were measured and found to be virtually identical.<<ETX>>
