Computer analysis of the fan doublet antenna
From EMP technical meeting; Kirtland AFB, New Mexico, USA (25 Sep 1973). The EMP response of the fan doublet, an hf-vhf communications antenna that resembles a bow tie viewed from broadside, was measured using a biconic simulator that produces a peak field strength at the antenna of 5600 V/m. Computations for comparison with the experimental data were performed, modeling the antenna with an integral equation approach in the frequency domain and Fourier transforming the data to the time domain to deterinine the transient response of the antenna. Results were obtained for the antenna located in free space and over a finitely conducting ground plane, the latter employing a modified image approach based upon the Fresnel plane wave reflection coefficients to model the antenna-ground interaction. The effect of the ground-reflected field is demonstrated. Effects of various load conditions are investigated using a time-domain integral equation approach. (auth)
