TECHNICAL DESCRIPTION

Main Claim

A broadband antenna comprising a reflector-constituting plane and, in the vicinity of said reflector-constituting plane, at least one transmit/receive radiating element,said antenna further comprising, disposed substantially in superposition on said reflector-constituting plane and said transmit/receive radiating element, an assembly of defective EBG (Electromagnetic BandGap) material elements, each substantially plane defective EBG material element being parallel to said reflector-constituting plane, and at least one of the characteristics of magnetic permeability, of dielectric permittivity, and/or thickness in the direction perpendicular to said reflector-constituting plane being substantially different from one defective EBG material element to another, the assembly formed by said reflector-constituting plane and said assembly of defective EBG material elements forming a leaky resonant cavity.

BENEFIT

• Larger frequency band (broadband)
• High directivity– low side lobs
• Compact size (flat antenna)
• Low weight
• Good gain to size ratio
• Multifunctional (multi-polarisation, multiband (f0, 3f0, 5f0…))

INDUSTRIAL APPLICATIONS

• High frequency antenna with a high bit rate
• Antenna 2D to replace 3D antennas (the dish type or lens type)
• Antenna for on-board applications of civil (point-to-point link) aerospace or military type
