Transient Response Optimization of Ultra Wideband Antennas (Using Particle Swarm Optimization)

Original language description

For some ultra wideband applications (i.e. radar, positioning, etc.), it is crucial to know the transient responses of antennas. Optimization process searches for the dipole shape, which accomplishes two required parameters - namely good matching and minimal distortion. The dipoles have derivative characteristics. The distortion is evaluated from the derivative of the excitation impulse with the radiated impulse. The particle swarm optimization method was used in the process of optimization. This methodwas implemented in MATLAB&reg;, where the antenna structure is generated. The antenna is ubsequently simulated in the CST Microwave Studio&reg;. The optimized ultra wideband dipole is perfectly matched and minimally distorts the applied signal.

Optimalizace vyzareneho impulsu UWB antenou (pomoci optimalizacni metody PSO)

Czech description

Pro nektere UWB aplikace (radary, urcovani polohy, aj.) je velmi dulezite znat tranzientni prubeh vyzareneho impulsu antenou. Optimalizacni proces hleda tvar dipolu, ktery by mel byt dobre prizpusoben a minimalne zkresloval vyzarovane impulsy. Zkreslenije vyhodnocovano jako podobnost derivace budiciho impulsu s vyzarenym impulsem. Pouzita optimalizacni metoda PSO byla implementovana v MATLABu, ve kterem byla take vytvarena anteni struktura pro nasledny vypocet jejich parametru v CST Microwave Studiu. Zoptimalizovany UWB dipol je perfektrne prizpusoben a minimalne zkresluje vyzarovany impuls.
