Abstract :
A new design approach for a pod-mounted omnidirectional antenna was developed. It is a traveling-wave antenna with high conformability, strongly coupled with the instrument pod to enable it to circumvent the Chu limitation on the gain bandwidth due to antenna size. Scale model experiments exhibited impedance bandwidth up to 20:1 and gain pattern bandwidth of 10:1. Research is continuing, and considerable improvement in performance can be expected since the development is in its early stage and several potential improvements are obvious and straightforward.
