Abstract :
On the basis of a modified form of Mei´s integral equation, which includes dielectric effects using the quasistatic approximation theory proposed by Popovic (1984), the input impedance and the radiation patterns of several quadrifilar helical antennas with axial or normal mode are investigated. The theoretical results agree quite well with experiment
