Loaded antenna in half lossy space base on HDGA

摘要

Antenna loads can modify the current distribution on the wires,thus improving antenna characteristics in the process.However,it is difficult to calculate appropriate loads of antenna near the ground because in half lossy space there are inherent situational complexities.This paper optimizes loads of antenna near the ground base using a half-determined genetic algorithm.The numerical results show the HDGA has a quicker convergent speed and a better convergent value than the SGA.
