Abstract
A 1.5-turn balanced helical antenna is numerically and experimentally investigated. It is found that the helix has a smoothly decaying current distribution to radiate a circularly polarised wave. Further study shows how the mutual coupling between a pair of identical helixes can be reduced by rotating one helix with respect to another.Keywords
