A Broadband VHF-L Band Cavity-Backed Slot Spiral Antenna
Abstract
Slot spiral antennas offer the possibility for very thin and conformal designs. This report covers the physical characteristic of a cavity-backed slot spiral, as well as the associated infinite balun and termination designs. The report traces through the development and characteristics of a 6 inch and 18 inch version of the slot spiral. Simulations and measurements of various cavity-backed spirals are presented and used to optimize the antenna's computations. Several options for miniaturizing this design using capacitive and inductive loadings are also presented.
