Abstract

The presented text deals with design of the modification of the low-profile dipole planar inverted cone antenna (LPdiPICA), which is originally modified. The motive of the antenna was designed in CST Microwave Studio and optimized in the MATLAB by the particle swarm optimization method (PSO) and originally modified genetic algorithms (GA). The parameters s₁₁ was wideband optimized in frequency range from 3 GHz to 7 GHz. In the first part, the basic motive of the coplanar antenna is described. In the second part, the global optimization of the antenna by PSO and GA is proposed. In the third part, the numerical example is shown: an antenna optimized wideband frequency range from 3 to 7 GHz. The best antenna is then solved from 1 to 10 GHz.
