Comparison between Horn and Bow-tie Antennas for Through-the-Wall Applications

The aim of this paper is a direct comparison between: 1) a double-ridged horn antenna; 2) the same double-ridged horn filled with sawdust; 3) a bow-tie antenna operating in (approximately) the same band (0.5 GHz 1.5 GHz). The three antennas have been simulated and experimentally tested. The best performances in terms of capability to detect a target behind a 40 cm wall have been obtained with the horn antenna filled with sawdust.
