Abstract

The invention provides a cavity antenna (1) and is suitable, for example, for application as a communication antenna. The antenna (1) comprises a cavity (2) with dielectric (7), an aperture (4) arranged in front of the cavity (2), and a feed element (5). According to the invention, the dielectric (7) is provided with hollow spaces (14) containing electrically conducting shells (15). By introducing such a dielectric, the radar target cross-section of the antenna can be reduced and the antenna is made less space-consuming and lighter.
