Abstract
A lightweight broadband blade antenna assembly is incorporated into the surface of an airfoil, such as a structure component of an aircraft, or a separate airfoil (blade antenna) attached thereto. A first metallized area is formed on the airfoil adjacent a leading edge of the airfoil. A second metallized area is formed on trailing edge of the airfoil and is spaced from the first metallized area by a first gap which is configured to provide a capacitive coupling between the first and second metallized areas. A third metallized area is formed on the cap portion of the airfoil and is spaced from the first metallized area by a second gap and is electrically connected in series with the first and second metallized areas. RLC circuits are electrically connected across tuning gaps formed in the third metallized area to provide a broadband response.
