Research output: Contribution to journalArticlepeer-review

Abstract

The axial ratio and the radiation pattern of a dual spiral antenna improve as the feed wire length is shortened. The bandwidth for circular polarisation within an axial ratio of 3.0dB is estimated to be 1:1.35 for a feed wire length of zero.
