Abstract :
This paper introduces a novel design to enhance the directivity of a low profile antenna for distance measuring equipment (DME) avionic system. A horizontal grooved ground plane is used to improve the antenna directivity. The proposed design has a height of lambda/10. Its radiation pattern is comparable with a monopole of lambda/4 on the same ground plane size. Hence, with the use of a low profile antenna we can reduce the aircraft air drag without any significant change in its radiation characteristics.
