提出了一种新型的一维频率扫描双缝隙波导阵列天线，该天线具有扫描体积大、频率灵敏度高、交叉极化小、副瓣低等优点。电磁波通过单脊蛇形波导侧腔上的漏波双缝辐射。通过适当设计起延迟线作用的蛇形波导，这种一维频率扫描阵列天线可以在9.7 ~ 10.3GHz的频率范围内实现39°扫描，并具有65°/GHz的高频率灵敏度。设计了相邻单体同向倾斜的双缝结构，以获得较低的交叉极化，避免高阶模辐射。在整个工作频带上，交叉极化比相应的共极化低45 dB。泰勒孔径分布用于实现低旁瓣（−21 dB）。非谐振驻波比低于1.2，同时谐振驻波比保持在2.5左右的低水平。此外，我们提出的一维阵列作为一个积木可以组成一个新的二维电扫描阵列，频率扫描在一维和相位扫描的正交维。对一个由三个波导单元组成的二维阵列进行了仿真，预测了相位扫描性能，结果表明可以获得120°的扫描性能。最后，制作了一个一维双缝波导阵列天线，测试结果与仿真结果吻合较好。
This paper presents a novel one-dimensional (1D) frequency scanning dual-slot-waveguide array antenna with versatile advantages such as large scan volume, high frequency sensitivity, low cross-polarization and low sidelobe. Electromagnetic waves radiate through the leaky-wave dual slots, machined on the side chambers of the single-ridge serpentine waveguide. By properly designing the serpentine waveguide, which plays the role of delay line, such 1D frequency scanning array antenna can achieve 39° scanning over a frequency range from 9.7 GHz to 10.3 GHz, and high frequency sensitivity of 65°/GHz. The dual slots with all the adjacent monomers inclined in same direction are designed to acquire low cross-polarization and avoid high-order mode radiation. The cross-polarization is 45 dB lower than the corresponding co-polarization over the whole working band. Taylor aperture distribution is employed to achieve a low sidelobe (−21 dB). The nonresonance VSWR is below 1.2, and meanwhile the resonance VSWR remains a low level, around 2.5. Furthermore, our proposed 1D array as a building block can compose a novel 2D electric scanning array, with frequency scanning in one dimension and phase scanning in the orthogonal dimension. A 2D array consisting of three waveguide elements is simulated to predict the phase scanning performance, and the results indicate that a 120° scanning performance can be obtained. At last, a 1D serpentine dual-slot-waveguide array antenna is fabricated, whose measurements show good agreement with simulations.
