MEHRFACHSTRAHLANTENNE MIT PHOTONISCHEM BANDLÜCKENMATERIAL |
摘要 |
A system includes a device for focusing electromagnetic waves, and a multiple-beam antenna. The antenna includes: a photonic bandgap material ( 20 ) having at least one band gap, at least one periodicity defect ( 36 ) of the photonic bandgap material so as to produce at least one narrow bandwidth within the bandgap material, and excitation elements ( 40 to 43 ) for transmitting and/or receiving electromagnetic waves within the at least one narrow bandwidth, the elements being arranged relative to one another so as to produce overlapping radiating spots. |
