Conformal antenna array produced on a metal semi spherical surface is composed of 40 equal microstrip patch antenna elements of performance. These antennas are characterized by small physical sizes, simpicity of construction mounting and low cost. Round microstrip patch antenna array are distributed by semi sphere, forming a geometrical shape of loxodrom. The antenna array elements are built for the central frequency of 1,6 GHz. This way of pacing the antenna elements allows rotating of the main lobe throughout the hemisphere (360º), in addition to the radiation pattern does not change, as well as the antenna gain. It is necessary to focuse a lot of attention, in order to achieve that, on the creation of identical microstrip patch antennas, their proper placing by semi spherical as well as the performance of initiatives of all antenna elements. To excite a larger number of antenna elements with equal power, as part of this work was created power divider 1 to 32, Wilkinson performance. This power divider provides to each antenna elements the same power without entering amplitude and phase transition. Over each microstrip patch antenna array have been determined S11 parametar, if there were deviations in the parameters, it was exercised the restatement in mounting the antenna or it was replaced by a new one. We have measured radiation pattern on this made antenna array for different number of excited antenna elements. The resulting radiation patterns are compared with the calculated radiation patterns in a computer program that was not developed as part of this study. Although there are some deviations, the calculated and measured radiation patterns are largerly consistent. The fact that the measurements were not conducted in the chambre without electromagnetic interference it should not be ignored.
