Abstract :
This paper presents a parametric study of microstrip antennas fed by conductor-backed coplanar waveguides in order to avoid excessive power lost in parallel-plate modes (PPMs). The calculation of power lost in PPMs and radiated power compared to return loss measurements permits to deduce general rules to limit spurious effects due to PPMs.
