摘要

本文讨论了用于全波段超宽带无线电应用的物理小且成本有效的印刷天线的设计和优化。采用遗传算法辅助优化实现物理尺寸和全频段操作。天线采用印刷槽切式散热器固定在梯形接地面上,天线尺寸为21.6mm × 18.8mm × 1.6mm。原型天线性能符合FCC规定,在2.1GHz - 13.2GHz频率范围内阻抗带宽为10 dB或更好,具有合适的全向辐射方向图。

Design of a small ultra wideband antenna using a genetic algorithm approach
This paper addresses the design and optimisation of a physically small and cost effective printed antenna for full-band UWB radio applications. A genetic algorithm assisted optimisation is used to achieve the physical dimensioning and full-band operation. The antenna is realized as a printed slot cut radiator fixed over a trapezoidal ground plane, the antenna dimensions are 21.6mm × 18.8mm × 1.6mm. The prototype antenna performance is in line with the FCC regulations, with an impedance bandwidth of 10 dB or better across the 2.1GHz - 13.2GHz frequency range, and a suitable omni-directional radiation pattern.
