Abstract :
Two types of antennas are investigated: a diode-loaded helix antenna and a diode-loaded spiral. The changes in the polarisation behaviour are compared with conventional helix antennas and spirals by using the polarisation characteristics. Fairly good agreement is found between calculated and measured polarisation characteristics.
