7. Compared to the two conductor antennas we have used earlier (see Ref. 2), this design is slightly more k selective and allows better coupling to coaxial-coplanar probes.

11. We assume a surface current distribution, located on antenna plane y = h [see Fig. 1(a)]. Moreover, in agreement with numerical calculations, we consider the current to be uniform along the width of every conductor.

13. 0 leads to a decrease of the k selected, with the result being a phase decrease.
