A pattern shaping synthesis method along with a new sidelobe shaping scheme are used to design antenna arrays capable of delivering a much better radiation performance in terms of homogenous coverage and reduced interference with respect to commercial antennas. For verification, radiation within an urban scenario for the region inside and outside the cell has been studied with the aid of a 3D ray-tracing simulator. Results show a 15% radiation reduction outside the cell for the synthesized antenna with respect to commercial antennas under equal coverage conditions.
