An antenna design for PANSAT using NEC.
antennadesignfor00ellr.pdf (4.912Mb)Abstract
In this thesis the Numerical Electromagnetics Code (NEC) is used to design an omnidirectional antenna for the Petite Amateur Navy Satellite (PANSAT). The completed antenna design uses a tangential turnstile antenna to achieve a circularly polarized radiation pattern with predicted worst nulls of approximately -3.0 dBi. The use of NEC-3, recently ported to 80386 personal computers, demonstrates the potential of personal computers for performing this type of design work. A simple antenna feed system was also designed. Performance predictions for the completed antenna system were made through the applications of simple statistical functions to the NEC output.
