Directed rounded-edge bow-tie antenna for Direction Finding at Ultra High Frequencies

In this paper, we propose a novel antenna that is a directed rounded-edge bow-tie antenna which is inclined from both sides to demanded direction with an angle. Producing of rounded-edge bow-tie antenna is low cost and it can be easily built. Furthermore, it works fine for a wideband frequency range. Therewithal, one can use it for the mobile applications. The aim of the bending the antenna is to utilize the directionality of the antenna for finding the direction of the radio signal sources at UHF. Performance of the antenna is still elegant even if the rounded-edge bow-tie antenna is bended in such manner that the metal sheets have an angle less than 180 degrees relative to each other.
