“…The design of phased array antennas is a key issue in order to guarantee high efficiency, reliable, and cost-effective deployments for long-range WPT systems [34]. Unlike in communications and radar applications, the goal of a WPT system is the maximization of the end-to-end power transfer efficiency.…”

“…The Bottom layer is etched into the two slots, which is equivalent to the introduction of reactance, and thus the microstrip antenna has two resonance points [12] . Considering the impedance matching of the interface, the width of the microstrip line can be calculated by the empirical formula (4).…”

Internet of Things (IOT) is the third change of the world information industry after computer and the Internet. It refers to the various kinds of information sensor (equipment), real-time acquisition of information that requires monitoring, connection, interactive objects or processes, etc., which then emerges as a huge network. It is used to realize connection between object and people, object and object, and goods and the network, to facilitate the identification, control and management [1] . It can be expected that the development and application of IOT will bring huge changes to daily life, industrial and agricultural production, and military. And as an "organ" of IOT -wireless sensor is an essential component of the IOT [2][3] . How to provide energy for the number of sensors, a wide variety of functions, will be a challenge for the designing and planning of IOT.First of all, the wireless makes it impossible to supply power through traditional wire.Secondly, if a battery is applied to power a wireless sensor, to guarantee the sensor's performance, frequent examination and change would be necessary for the sensors distributed in different network nodes.Moreover, there are many sensors that may be distributed in the areas that are difficult to maintain, narrow spaces, airtight places, water, fine pipes etc [4][5] . If energy is provided by the wireless energy transmission, the above-mentioned problems can be easily solved with the help of a large capacity storage device and battery detection device. The sensors can be maintained and charged automatically, reduce the workload of the Internet of Things by a great deal and improve the reliability of the network [6][7] . In addition, compared with the traditional wired energy transmission, wireless energy transmission technology boasts of the following advantages: 1) In flammable, explosive, high temperature and other harsh environment, wireless energy transmission can avoid risks like electric spark, line aging and other security; 2) For long distance energy transmission, it can cut cost and transmission line will be unnecessary. 3) Wireless energy transmission can avoid complicated wiring work, save the space required for wiring, simplify the installation of the system and reduce the cost of the system. The research of wireless power transmission is very important for the development of the IOT technology and practical application. In particular, the microwave energy transmission of antenna technology is becomResearch of Antenna for Microwave Energy Transmission System for IOT Wu Qin* Tianjin Railway Technical and Vocational College, Tianjin, ChinaABSTRACT: This paper is oriented to the specific networking applications of wireless energy transmission system.

“…To reduce the kinds of amplifiers, Baki et al and Li et al [7,8] proposed the isosceles trapezoidal distribution (ITD) and stepped-amplitude arrays (SAAs), respectively. The design and implementation of transmitting array could be greatly simplified if all elements are uniformly excited [9]. The random-located uniformamplitude array (RLUAA) comprising of 100 elements was optimized by particle swarm optimization (PSO) algorithm with a BCE of 89.96% being obtained [10].…”

Beam capture efficiency (BCE) is one key factor of the overall efficiency for a microwave power transmission (MPT) system, while sparsification of a large-scale transmitting array has a practical significance. If all elements of the transmitting array are excited uniformly, the fabrication, maintenance, and feed network design would be greatly simplified. This paper describes the synthesis method of the sparse uniform-amplitude transmitting array with concentric ring layout using particle swarm optimization (PSO) algorithm while keeping a higher BCE. Based on this method, uniform exciting strategy, reduced number of elements, and a higher BCE are achieved simultaneously for optimal MPT. The numerical results of the sparse uniform-amplitude concentric ring arrays (SUACRAs) optimized by the proposed method are compared with those of the random-located uniform-amplitude array (RLUAA) and the stepped-amplitude array (SAA), both being reported in the literatures for the maximum BCE. Compared to the RLUAA, the SUACRA saves 32% elements with a 1.1% higher BCE. While compared to the SAA, the SUACRA saves 29.1% elements with a bit higher BCE. The proposed SUACRAs have higher BCEs, simple array arrangement and feed network, and could be used as the transmitting array for a large-scale MPT system.
