Abstract

A continuous transverse stub (CTS) array antenna with broad bandwidth and high-power handling capacity is proposed in this paper. The technologies of multi-step impedance matching and T-shaped electromagnetic band-gap (EBG) loading are utilized, which improved the antenna operating frequency bandwidth. An H-plane lens horn is used to feed the CTS array. As a result, a good bandwidth capability of more than 32% is achieved, with a gain variation less than 3.0 dB. The measured sidelobe level (SLL) is below -18 dB in the entire frequency range. Moreover, the power handling capacity of the antenna is more than 80 MW and can reach the GW level after arraying, which indicates that this antenna has application potential in the high-power microwave (HPM) field.

摘要

本文提出了一种具有宽带宽和高功率处理能力的连续横向短截线（CTS）阵列天线。采用了多步阻抗匹配和T形电磁带隙（EBG）加载技术，改善了天线的工作频率带宽。使用H面透镜喇叭对阵列进行馈电。结果，实现了超过32%的良好带宽能力，增益变化小于3.0 dB。在整个频率范围内，实测旁瓣电平（SLL）低于-18 dB。此外，该天线的功率处理能力超过80 MW，阵列后可达到GW级别，这表明该天线在高功率微波（HPM）领域具有应用潜力。
