Abstract
A probe-fed rectangular DRA is investigated and compared with two non-canonical structures, whose geometries can be seen as deviations from the parallelepiped. It is shown that these advanced geometries exhibit a larger impedance bandwidth than the canonical RDRA, while the rest of their properties are largely unchanged. In addition to that, the new structures do not require lengthy and complex fabrication procedures due to their relatively simple shape and feeding scheme. Finally, since these shapes are derivations from the rectangular geometry, similar modes are excited and hence their overall performance can be described and designed starting from the analytical expressions for the parallelepiped.
