[en] This paper reveals a novel stacked slotted bow-tie antenna element with a large bandwidth resonating at 11.7 GHz for satellite TV broadcasts. The simple, cost effective antenna is built on common dielectrics and is a layered version of the popular patch antenna. It is shaped in a bow-tie and converted into the slotted version in order to increase the antenna radiating surface. The dual polarized antenna element offers a large directivity of 7.2 dBi in the farfield direction. It is terminated with a coplanar waveguide feedline which is ideal to preserve its large bandwidth in an antenna array configuration. In order to appreciate its results and its design simplicity, a comparison of its S-parameters, radiation patterns, E-fields and H-fields are made with five other popular elements at the center frequency of 11.7 GHz.
