多波段分形天线无线通信

文摘

更广泛的带宽在现代无线通信中是必需的。通常每个天线在一个频段,在不同的天线需要不同的应用程序。这将需要更多的空间为职业。介绍了一种新颖的多波段分形天线无线通信。分形自相似的形状和空间填充属性。这个属性使分形天线紧凑和操作在多波段的频率。分形天线是由应用生成器形状重复以恒定比例因子和结果与对数周期天线的特点是多波段天线小型化的特点。ISM波段(工业、科学和医疗乐队)和GSM乐队主要是使用无线乐队。提出了分形结构的操作频率覆盖两个GSM乐队和一个ISM波段。Sierpinski模拟和闵可夫斯基分形结构。 Fractal with PIFA structure compromise size reduction. PIFA is one of the most promising antenna types because it is small and has a low profile, making it suitable for mounting on portable equipment. Sierpinski-PIFA gives 35% size reduction and 60% size reduction is possible using Minkowski- PIFA structure. The radiating element is etched on Nalco substrate with dielectric constant of 4.2. The Antenna was simulated using CST Microwave Studio based on FDTD method. Antenna design is discussed in detail and results obtained are presented here.
