To obtain maximum beam pattern, the primary radiator is placed ______

1.	To obtain maximum beam pattern, the primary radiator is placed ______ in a reflector antenna.(a) between Focus and Directrix(b) after the focus(c) at the focus point(d) can be placed anywhereThe question was posed to me during an online interview.I'd like to ask this question from Feeding Systems in portion Reflector Antenna of Antennas
Answer» The CORRECT option is (c) at the focus point Explanation: Maximum beam pattern is obtained only when the feed is placed at the focus of the parabola. Reflector antenna is a high gain antenna. So this is ONE of the important POINTS to obtain the maximized gain.
