| Abstract: | Most broadband microstrip antennae are implemented in the form of slot structure or laminate structure, which provide a broad impedance bandwidth and meanwhile bring large sidelobes and backlobes. A novel uni-planar compact electromagnetic band-gap(EBG) structure is proposed, which shows excellent performance when applied to broadband stacked or aperture coupled microstrip array antennae. The test results indicate that, the directivity is effectively improved, and the front-to-back ratio is increased, and the thickness of the antenna is reduced. These improvements make this structure better used in airborne antennae. |
