摘要

设计用于超宽带(UWB)应用的天线应该提供更宽的带宽和最小的脉冲失真。其中一种满足这些要求的天线就是维瓦尔第天线。在传统的维瓦尔第天线中，辐射耀斑被限制为指数型。本文采用傅立叶级数法设计了槽载维瓦尔第天线。在这里，剖面的几何形状不受限制，并采取优化的形状，以满足最小反射系数(Su)的最大增益的目标。仿真结果与硬件样机测量结果吻合良好，验证了所提出的设计理念。

Tapered slotted Vivaldi antenna design using Fourier series approach for UWB applications

Antenna designed for ultra wide band (UWB) applications should offer a wider bandwidth with minimum distortion of pulses. One such antenna which meets these requirements is the Vivaldi antenna. In a conventional Vivaldi antenna the radiating flare is restricted to take an exponential profile. This paper presents the design of slot loaded Vivaldi antenna, using Fourier series approach. Here the geometry of the profile is not restricted and takes an optimized shape, to meet the objective of maximum gain subject to minimum reflection coefficient (Su). Antenna performance obtained from simulations and hardware prototype measurements shows good agreement, which verifies the proposed design concepts.
