A modification of the famous Bow Tie antenna element for wideband Direction-Of-Arrival estimation antenna arrays is designed. A broadband impedance match from 5 GHz to 14.5 GHz corresponding to a 97% bandwidth, as well as a very stable radiation pattern over a 37% bandwidth from 5.5 GHz to 8 GHz is achieved. A method for pattern stabilization using… CONTINUE READING
