摘要：

提出一种新型的大带宽脊形接地板微带贴片天线.天线采用空气介质层，通过在脊形接地板顶端用同轴探针馈电单层方形贴片，从而减小了探针电感,能获得很宽的工作带宽.该天线的实测VSWR≤2阻抗带宽达到了90.1%，覆盖1.75 ～4.62 GHz的频率范围.

Abstract:

novel large-bandwidth square patch antenna with ridge-shaped ground plate is proposed. The patch is on an air substrate and excited by a coaxial probe that is stretched from the top of a ridge-shaped ground plate so that the probe inductance is reduced and the broadband operation is obtained. The measured impedance bandwidth with VSWR≤2 reaches 90.1%, covering a frequency range of 1.75～4.62 GHz.

Key words: large-bandwidth, radiation pattern
