TLDR
In this paper, an experimental study at X-band of a dipole-excited short backfire antenna having corrugations on the main reflector rim was conducted. The results obtained show that the presence of the corrugation can lead to improved antenna gain and sidelobe levels.Abstract:
This letter reports results of an experimental study at X-band of a dipole-excited short backfire antenna having corrugations on the main reflector rim. The results obtained show that the presence of the corrugations can lead to improved antenna gain and sidelobe levels.read more

Circular short backfire antenna modeling
TL;DR: In this article, the first three-dimensional analysis of a short backfire antenna (SBA) was described using the vector-mode-matching method, which is efficient for a model that uses only the first harmonic, cos phi, and deforms the path of numerical integration.
