摘要

摘要: 在超寬帶TEM喇叭天線的設計中，往往由于低頻性能優(yōu)化和天線小型化兩者難以兼顧，而使得其應用受到限制。該文針對低頻的反射問題，基于帶通濾波器并聯(lián)的設計思路，且區(qū)別于傳統(tǒng)天線末端的低頻反饋回路結構，提出在超寬帶TEM喇叭天線饋電過渡結構上設計低頻分離回路結構，減少低頻分量在天線末端的反射，從而改善天線的低頻性能。采用該設計思路，對一款超寬帶TEM喇叭天線的結構進行改進并實現(xiàn)其優(yōu)化設計。通過對比改進前后的天線性能，其阻抗帶寬的低頻降至0.1 GHz，拓展了12.5%，同時天線端口饋電效率提升10%，結果驗證了該設計思路和方法對于超寬帶TEM喇叭天線低頻優(yōu)化的有效性。最終，對阻抗特性以及該結構在不同頻點下電流分布的分析，進一步證實新思路的可行性。

Abstract: In the design of ultra wideband TEM horn antenna, it is difficult to combine both the character optimization in low frequency and the miniaturization of an antenna, which always limits the usage of TEM horns in some applications. For the problem of low-frequency reflection, a structure, which is referred to the principle of band-pass filters in parallel and different from the conventional ones, is proposed in this paper for separating a fraction of low-frequency electric field component on the plates linking excitation port to radiation plates. It can greatly reduce the reflection of low-frequency component at the edge of radiation plates to improve the low frequency character of the antenna. In this paper, an ultra-wideband TEM horn antenna improved with the proposed structure is presented. Finally, the comparison of the improved antenna and the original one is exhibited, which shows that the impedance bandwidth is 12.5% wider with the low-cutoff frequency decreasing to 0.1 GHz and simultaneously the port-feed efficiency is increasing by 10%. The results confirm the validity of the proposed design to optimize the low frequency character. The feasibility is also validated in the end by analyzing the impedance and the magnitude distribution of currents in different frequencies, respectively.
