| 摘 要： | A metallic photonic bandgap (MPBG) resonant antenna is introduced,which has novel characteristics (such as high directivity and high radiation resistance for a certain range of frequencies )as compared to conventional MPBG antennas.The linear MPBG resonant antenna is formed by infinitely long metallic rods in vacuum.The numerical results for the radiation pattern and the radiation resistance are presented.By adjusting the structure of the MPBG resonant antenna and its working frequency,an optimal structure is achieved.The physical reasons for the novel characteristics of the MPBG resonant antenna are also explained.
