折号的发送。20世纪1906年,恩斯特前锋亚历山德森展示了第一款连续波(CW)无线电的无线电信号的产生和传输。此实现信号的开头的现代无线电通信,其中无线电波控制其中的各个方面。在20世纪初,约1922年,被认为是雷达的诞生的时间。雷达洛斯阿拉莫斯科学实验室作为曼哈顿计划在二战期间有了重大技术的发展,对盟军的成功是至关重要的。雷达发出无线电波的检测和对物体位置的无线电波的反射。这种反射可确定一个对象的位置和速度。军事雷达的意义很快就被理解,所以很多早期的发展笼罩在秘密。由于RFID是无线电广播技术和雷达的结合,它是衔接这两个单独的学科,但RFID的想法并不令人意外。一个观念的起源有一个古老的格言,成功有许多父亲,但失败是一个孤儿。技术的发展是凌乱的。拥有巨大的潜力,更广泛的让人确定技术演变方向。人们一直不承认,直到后来,找到了明确的证据,人们才承认这一事实。课本上的知识是完美或说是合乎逻辑发展,而且往往将技术发展的时间提前。探索RFID是由哈里·斯托克曼,里程碑式的论文“利用反射功率的通信”开始的,他表示,“很明显,还有许多工作开发工作和大量的研究需要做,之前遗留在反射电力通信中的基本问题解决,并可以开始在应用领域的探索。”三十年之前,能通过哈里的研究达到修成正果。其他方面的也需要发展,例如:晶体管,集成电路,微处理器,通信网络的发展和商业格局的变化。这是一个不小的任务和许多事情一样,时机就是一切。因此RFID的成功将不得不等待一段时间。自哈里·斯托克曼的研究之后发生了很多事情。20世纪50年代是探索RFID技术就像在20世纪30年代和40年代的无线电和雷达技术发展的时代。世界探讨一些RFID相关技术,如远程飞机“识别朋友或敌人”(IFF)转发器系统。在20世纪50年代的技术发展,包括佛罗里达州弗农的“应用微波零差”和DB哈里斯的研究“无线传输系统的调制的无源应答器”。导致RFID发展的车轮再次转动。1960年到20世纪80年代:RFID成为现实。20世纪60年代到20世纪70年代是RFID爆炸的前奏。在963-1964年RF哈灵顿研究RFID相关的论文“使用主动散射体”和“装散射理论”中的电磁理论在进行实地测量。世界上出现了与许多RFID技术相关的发明,如1963年罗伯特·理查森的“远程激活的无线电频率供电装置”,1969年奥托Rittenback的“通信雷达梁”,1968年JHVogelman的“利用雷达波束被动式数据传输技术”和1967年JPVinding的“读写器应答识别系统”。接着商业活动在20世纪60年代开始。Sensormatic和Checkpoint成立于20世纪60年代后期。这些公司,开发的电子物品监控(EAS)设备反盗窃,其他如Knogo,。这些类型的系统往往采用与'1位'标签-只可检测到的标记的存在或不存在,而且可以作出标记,是廉价且有效的防盗措施。这些类型的系统使用,也关系到微波或电感的技术。EAS可以说是最普遍的商业使用RFID。在20世纪70年代,发明家,企业,学术机构,和政府实验室工作积极开发RFID,因此此项技术有显着的进步。特别是研究实验室和学术机构,如洛斯阿拉莫斯科学实验室,西北大学(NorthwesternUniversity),以及微波研究所基金会在瑞典的出现等等。早期的重要发展是在1975年的洛斯阿拉莫斯国家实验室由阿尔弗雷德Koelle的,史蒂芬·德普和罗伯特Freyman提出的“遥测使用调制散射的短距离无线通信”的电子识别。大公司也开始开发RFID技术,比如雷神公司在1973年开发的“Raytag”。在1975年RCA和飞兆半导体则活跃的在与理查德KlenschRCA开发的“电子识别系统”,在1977年F.SterzerRCA开发的电子车牌。托马斯·迈尔斯和阿什利·雷飞兆半导体还在1978年开发出“被动编码微波转发”。纽约和新泽西港口管理局还测试由通用电气,西屋电气,飞利浦
