Abstract :
Two new resonant antennas are discussed: 1) A bifilar helix with antiphase feed that radiates a \\sin \\theta shaped, circularly polarized pattern with the null perpendicular to the helical axis; and 2) a quadrafilar helix with feed currents in quadrature that radiates a cardiod shaped, circularly polarized pattern.
