Abstract

This study presents a new structure for planar aperture antennas with a very simple configuration by making use of gap waveguide technology. Applying the concept of H-plane horn in both feeding network and radiating layer results in a flat configuration capable of providing a directive radiation with reasonable impedance bandwidth, high gain and low side lobes. The proposed structure introduces a very simple configuration, which does not face the enhancement of design and fabrication complexity for larger apertures and higher gains. The principle of operation and design procedure for both the radiating layer and feed network are fully discussed in detail. A sample is designed to operate at Ku band, which presents proper radiation performance with the maximum gain of 24.5 dBi, the maximum efficiency of 85% and the side lobe level (SLL) lower than −22 and −13 dB in H- & E-planes, respectively.

由脊隙波导喇叭激励的串联馈电H平面喇叭阵列组成的平孔径天线

利用间隙波导技术，提出了一种结构简单的平面孔径天线结构。将h面喇叭的概念应用于馈电网络和辐射层，可以获得具有合理阻抗带宽、高增益和低侧瓣的定向辐射的平面结构。所提出的结构引入了一个非常简单的配置，它不面临设计和制造复杂性的提高，更大的孔径和更高的增益。详细论述了辐射层和馈电网络的工作原理和设计步骤。设计了一种工作在Ku波段的样品，该样品具有良好的辐射性能，最大增益为24.5 dBi，最大效率为85%，H- &的旁瓣电平(SLL)低于- 22和- 13 dB;分别E-planes。
