Abstract

In this paper we present the design and simulation of a self-complementary (SCA)Ultra-Wideband (UWB)antenna. The basic structure of this antenna uses the Fibonacci sequence in the construction of a golden spiral in the first iteration and six hexagonal monopoles are strategically placed in the midpoints of the spiral to maintain the sequence. In addition, the microstrip feed line is partial expanded to implement a notch filter for acquiring ultra-wideband features. The self-complementary sequence engraved in the ground plane allows the smooth current distribution in the radiating patch and the multiple resonant frequencies. In the other hand, the composition and the structure of the proposed antenna guarantees the coexistence of the UWB and WLAN (5.15-5.825 GHz)technologies. The optimized dimensions for this antenna are 30 mm⨯23.3775 mm, with a bandwidth of 2.63 to 11.2 GHz with multiple resonant frequencies at 2.7-3.41-4.14-4.94-6.82-7.98-8.42-9-9.91-10.45 GHz with a VSWR <2 over the entire frequency range except for the rejected frequencies. The compact antenna has a quasi-omnidirectional radiation pattern with suitable input impedance and return loss less than −10dB over the UWB range, these features offer several applications within the telecommunications area.

基于斐波那契序列的多共振频率自互补天线在超宽带中的应用

本文介绍了一种自互补超宽带(SCA)天线的设计与仿真。这种天线的基本结构在第一次迭代中使用斐波那契数列构建黄金螺旋，六个六边形单极子被战略性地放置在螺旋的中点以保持序列。此外，微带馈线部分扩展以实现用于获取超宽带特性的陷波滤波器。刻蚀在地平面上的自互补序列使得电流在辐射贴片和多个谐振频率中分布平滑。另一方面，天线的组成和结构保证了UWB和WLAN (5.15-5.825 GHz)技术的共存。该天线的优化尺寸为30 mm，带宽为2.63 ~ 11.2 GHz，多个谐振频率为2.7-3.41-4.14-4.94-6.82-7.98-8.42-9-9.91-10.45 GHz，除被拒绝频率外，整个频率范围内的VSWR <2。紧凑型天线具有准全向辐射方向图，在UWB范围内具有合适的输入阻抗和小于- 10dB的回波损耗，这些特性在电信领域提供了多种应用。
