Abstract :
Several coupled slots antennas fed by a coplanar waveguide in uniplanar technology have been investigated using a full wave analysis. It is based on the use of integral equations technique solved by a 2-D method of moment. Theoretical results are compared to measured ones, and a good agreement is obtained for either return loss and the radiation patterns. Two configurations to match the coupled slots antenna to the coplanar waveguide are proposed.
