| Abstract: | In this paper, the band-stop characteristics of the electromagnetic band-gap (EBG) structure formed by triangular arrays of air holes on the dielectric structure is analyzed by the theoretical calculation and the measurements respectively, and the results are in agreement. According to the simulated and measured results, the co-mode EBG structure effectively suppressing surface wave for TE and TM modes is designed, and is also applied to the four-element microstrip patch antenna array. The measured results indicate that the impedance bandwidth of proposed antenna array is almost doubled, and the antenna gain is enhanced by about 1.3dBi. |
