Abstract

This paper illustrates a microwave dielectric tells design using genetic algorithms (GAs). A quarter-wave phase-compensating multidielectric lens, using four types of materials and a zoned structure is designed using GAs. The dielectric lens shape was designed using a GA with a random initial shape in order to compensate for the phase error of the multidielectric lens and achieve the required performance. The simulation result, which is performed using high-frequency simulation software (HFSS) from Ansoft, shows that the gain of the side lobes decreases 21-dB more when using our GAs designed multidielectric lens. as compared with the simulation result of the conical-horn antenna without multidielectric lens. The performance from -150degrees to 150degrees angles achieved improvement, which proves that GAs may be ail effective method for lens design. Further work will be done at this area.
