The present invention is a multi-element anti-jamming (A/J) antenna array. The antenna array includes a first antenna assembly configured for being fuse-mounted a first distance from an aft end of at least one of an artillery shell and a munition. The antenna array further includes a second antenna assembly configured for being fuse-mounted a second distance from an aft end of at least one of the artillery shell and the munition, the second distance being lesser than the first distance. Further, the antenna array includes multi-band functionality.
