A multiple flat sided modified Luneburg Lens antenna to provide a broadband and hemi-spherical coverage. The Modified Luneburg Lens antenna has a flat surface at the bottom and quadrilateral/hexagonal/octagonal/decagon/dodecagon flat surfaces at the sides (e.g., 'cupcake shaped') to manipulate the signal directivity of a radio frequency transmission or reception of interest in a plurality of octaves of bandwidth. The antenna may be configured with a Planar Ultra-Wideband Modular Array (PUMA) Antenna array structure with a broadband anti-reflective layer added between the two devices. The anti-reflective layer marries the two devices (lens and PUMA) and creates a broadband impedance matching between the new modified Luneburg lens antenna and dipoles of the PUMA array while maintaining the capability of the system to transmit and receive signals in a plurality of octaves of bandwidth.
