“…However, the added PIN diodes and the accompanying bias networks increase the complexity and manufacturing cost of the system [12,13]. A low radar cross-section (RCS) antenna with an improved receiving antenna performance has been reported, but the complicated antenna structure required to minimise the RCS is not suitable for a mobile DF system [14].…”

In this study, the authors propose a novel small antenna for use in mobile direction finding (DF) systems covering the range 20-1300 MHz. The proposed antenna has a multiconical sleeve to increase the input resistance at low frequencies while reducing the antenna size. A skirt-shaped disk on top of the antenna body maintains the omnidirectional radiation pattern over a wide frequency band without radiation nulls in the broadside direction. The detailed design parameters of the proposed antenna were optimised using a Pareto genetic algorithm (GA) with the FEKO EM software package. Below 200 MHz, the proposed antenna shows a receiving performance comparable to a 60-cm conventional dipole but at only half the size. Above 200 MHz, the antenna maintains an omnidirectional radiation pattern up to 1300 MHz with a stable realised gain, whereas the 60-cm dipole has a broadside radiation null at about 850 MHz.

“…In this paper, an ultrabroadband DF antenna array covering the whole UHF frequency range from 0.3 GHz to 3 GHz is introduced. Unlike the common antenna designs using dipols [1,2] the new design consists of ten vivaldi-type antenna elements to cover the UHF frequency range fully. The direction finding antenna array (figure 1) consists of ten vivaldi-type antenna elements, which are mounted in a circular array with an outer diameter of approx.…”
