提出了一种在多层印刷电路板上制作的具有宽工作频带的印刷L形探针天线。该天线为四层结构，包括电路层、接地层、探针层和贴片层。L型探头的印刷部分为调谐天线提供了额外的自由度，从而实现了宽工作频率。设计了一种中心频率为6.5 GHz的印刷L形探针天线，其测量阻抗带宽为40%，在整个工作频带内具有恒定的辐射方向图。
A printed L-probe antenna fabricated on a multi-layered printed-circuit-board (PCB) with a very wide operating band is proposed. This antenna is a four-layered structure, consisting of a circuitry layer, ground layer, probe layer, and patch layer. The printed part of the L-probe provides extra degrees of freedom for tuning the antenna, achieving a wide operating frequency. A printed L-probe antenna centered at the frequency of 6.5 GHz was designed with a measured impedance bandwidth of 40% with constant radiation patterns across the operating band.
