| Popis: | Implications and improvements of edge brightening effects led by $Q$ factor minimization restricted to keep the same level of directivity for high efficiency continuous circular aperture distributions are here reported. In this manner, an optimization strategy for a minimum $Q$ value–keeping the same level of efficiency and restricting the maximum sidelobe level ( SLL )– is envisaged. As application of the method, a design procedure devoted to reduce the $Q$ factor of the antenna aperture distributions while keeping a high level of efficiency is outlined. Then, these optimal Taylor distributions are used as initial point to develop an optimization strategy. This procedure is devoted to search Taylor-like distributions which offer a good compromise between low $Q$ factor and high efficiency values with potentials for the antenna design scenario, based on a decrease in edge brightening effects led by the minimization of the aforementioned $Q$ ratio. |
