Abstract :
This presented paper deals with the novel design of the Linearly Tapered Slot-line Antenna´s (LTSA) array for the Quasi-terahertz Molecular Spectroscopy application. Antenna array was designed for frequency range from 50 GHz to 600 GHz. The antenna is placed on a low lost dielectrically substrate Cuclad 217. The numerical model was analyzed in a EM solver CST Microwave Studio. After basic design, the antenna was optimized by own novel modification of SPC-PNX real-coded genetic algorithm. The wideband global optimization by SPC-PNX genetic algorithm of the broadband antenna for the mm-Band can be interpreted as original results.
