Abstract :
Two configurations are proposed for feeding printed dipoles with coplanar waveguide transmission lines. The coplanar waveguide feed is printed on a ground plane sandwiched between a high-permittivity substrate and a low-permittivity substrate which supports the antenna. Both linear and circular polarisation can be achieved. Measured results are presented.
