提出了一种新的线阵馈电方法，阐述了功分器、过渡段和发射器的使用，并保持了对阵元的均匀激励。这导致具有低损耗的高增益天线阵列，其设计简单、紧凑且便宜。所提出的馈电方法是基于激励驻波使用离散的金属贴片在一个简单的设计过程。作为概念验证，给出了具有两个和四个非线性元件的两个阵列，其分别提供12和的高增益，这接近于基于阵列理论的理论极限。两个阵列的辐射效率约为93%，这等于阵列元件效率，证实了馈电方法不会像标准方法那样增加损耗。为了便于制造过程，整个阵列结构都是3D打印的，这大大降低了制造和对准的复杂性。与现有的馈电技术相比，所提出的方法提供了更高的增益和更高的效率与更小的电气尺寸。
A novel feeding method for linear DRA arrays is presented, illuminating the use of the power divider, transitions, and launchers, and keeping uniform excitation to array elements. This results in a high-gain DRA array with low losses with a design that is simple, compact and inexpensive. The proposed feeding method is based on exciting standing waves using discrete metallic patches in a simple design procedure. Two arrays with two and four DRA elements are presented as a proof of concept, which provide high gains of 12 and , respectively, which are close to the theoretical limit based on array theory. The radiation efficiency for both arrays is about 93%, which is equal to the array element efficiency, confirming that the feeding method does not add losses as in the case of standard methods. To facilitate the fabrication process, the entire array structure is 3D-printed, which significantly decreases the complexity of fabrication and alignment. Compared to state-of-the-art feeding techniques, the proposed method provides higher gain and higher efficiency with a smaller electrical size.
