Abstract :
We have proposed and validated through simulations the possibility to interleave two pyramidal multi-band antennas. This new design enables to overcome bandwidth limitation problems as only one trap is now needed per radiating element on the radio navigation antenna. The feeding network is simplified as the two applications are now separated and polarizations can be defined independently for the two applications without significant impact on antenna design.
