Abstract
A new multi-band frequency response controlling method using groove loading technique on the narrow wall of an open-ended waveguide is proposed by the authors. The feature of this scheme is a larger stopband spacing that is independent of the position of the loading structure. A tri-band antenna is designed as an example to verify the effectiveness of the idea. Two notches are introduced, and the bandwidths, as well as stopband spacings, can be adjusted by independent parameters. The tri-band prototype can be fabricated using 3D printing technology or machining technology. Reasonable agreement between the measured and simulated results of impedance and radiation characteristics have been achieved.
作者提出了一种新的多波段频率响应控制方法，在开口波导的窄壁上使用沟槽加载技术。该方案的特点是止带间距更大，且与加载结构的位置无关。我们以设计三频天线为例，验证了这一想法的有效性。引入了两个凹口，带宽和止带间距可通过独立参数进行调整。三频原型可利用 3D 打印技术或机械加工技术制作。阻抗和辐射特性的测量结果与模拟结果之间达到了合理的一致。
