Abstract
The advantages of integrating an electromagnetic antenna into the skin of an aircraft and the constraints imposed on the materials are described here in two precise examples: an ultra broadband antenna for a counter-measure pod and an active antenna for X band radar. The first part of this paper shows the improved electromagnetic performances and the simplified production methods allowed by the integration of an omnidirectional spiral ultra broadband antenna into the radome, constituting the head of the counter-measure pod. The performances of the preliminary version, made up of a flat spiral antenna localized behind its hemispheric radome, are described as a reference. The various solutions used for the integration of the radiating spiral and its balun directly inside the hemispheric radome are then described, and the constraints applicable to the materials are given for each solution. The second part of this paper investigates the problems faced when integrating an X band active radar antenna. Finally, we examine the new possibilities available in the furtivity field.
