Projeto e otimização de antenas helicoidais não uniformes
=== In this dissertation, uniform helical antennas are used as a starting point to generate nonuniform optimized antennas . Improvements in the gain and input impedance are obtained by varying the helix shape using a second order polynomial function. The the polynomial approximation coefficients ar...
