本文提出了一种小型化的微带贴片天线，它具有增强的带宽。基于横向信号干扰的概念，采用双馈线结构来减小天线单元的非辐射边。为了扩展阻抗带宽，引入了附加的T形短截线谐振器。与典型的矩形贴片天线相比，该天线的尺寸减小了32%，阻抗带宽（S11<;-10 dB）提高了17.0%。可以观察到模拟和测量之间的良好一致性。
In this letter, a miniaturized microstrip patch antenna with enhanced bandwidth is presented. Based on the transversal signal-interference concept, the dual feedline structure is employed to reduce the nonradiating side of the antenna element. In order to extend the impedance bandwidth, an additional T-shaped stub resonator is introduced. Compared to a typical rectangular patch antenna, 32% size reduction and 17.0% impedance bandwidth (S11<;-10 dB) enhancement are achieved, respectively. Good agreement between simulation and measurement can be observed.
