<p>A multibeam antenna includes: a photonic bandgap material ( 20 ) having at least one band gap; at least one periodicity defect so as to produce at least one narrow bandwidth inside the at least one band gap of the photonic bandgap material, and excitation elements ( 50 to 43 ) for enabling electromagnetic waves to be received inside the at least one narrow bandwidth. The excitation elements are mutually arranged so as to generate radiating spots ( 46 to 49 ) partly overlapping on one surface of the photonic bandgap material.</p>
