Abstract

In this paper, we proposed a new broadband conical spiral antenna. This antenna adopted corrugated arms in the outer turns to improve low frequency operation. Tapered resistive loading along an exponential profile was also applied to suppress the reflected backward traveling wave which causes undesirable radiation characteristics in low frequency band. Characteristics of antenna components and parameters are provided along with guidelines and recommendations for miniaturization. The proposed antenna aimed to operate from 300 MHz to 1.2 GHz using 7 inch aperture and 6 inch height. Antenna characteristics were analyzed by FEKO simulations and simulation results will be presented.
