Complex Geometry Adaptive Antenna

The goal of the proposed research is to construct the Phase controlled directed antenna using low-loss dielectric and high relative permittivity material for the substrate. In this paper also presented two beams antenna. First part of the paper contains the simulation of such antenna using the software, based on the Finite Element Method for the purpose to find optimal parameters of such antenna before its construction. Our goal is to find the best parameters of the antenna, using the numerical experiment, to achieve desired radiation parameters: well matching to the open space; phase controlled narrow-beam; wide-band. There was designed phase controlled and two beams patch antennas at 7.6 GHz and 7.8 GHz respectively. Phase controlled antenna was archived by cutting patch antenna by half. Two beams antenna where made by cutting patch by two parts same type cutting corners from it. For simulation it was used 6.8 relative permittivity material for the substrate.
