In the structure, a low loss E-plane bent waveguide is used as slow-wave structure. The microstrip radiating antenna array is fed by a hybrid coupling technology. With this coupling, the energy is coupled from the waveguide slot to the microstrip array through the aperture. 此阵列采用一般的矩形波导形成慢波线结构,微带贴片天线构成辐射单元,通过混合馈电结构实现下层波导慢波线至上层微带贴片的能量耦合。
For UHF tag antennas design, using inverted-F and bent line-type structures can reduce the antenna size, the latter of which has become a mainstream design structure. 对于超高频标签天线设计,采用倒F和折线型结构都可以缩减天线尺寸,其中后者已经成为主流设计结构。
