Abstract
Quadrifilar helix antennas have gained attention recently as antennas for satellite telephone handsets. Here a modification procedure is introduced for decreasing the length of the quadrifilar helix antenna. Two modified and two non-modified, quadrifilar antennas are designed and measured. The measurement results are shown.
