The receiving module comprises transmitting (horn) and receiving antennas, rectifier, and power management unit. The receiving antenna is used at a frequency of 2.45 GHz which seems to be the most efficient one. The integrated system being low in weight is suitable to be placed on any system having a battery with recharging characteristics. The compact system is designed and simulated using CST STUDIO. The receiving module is used for the conversion of microwave power to DC power for the easy charging of a Quadcopter. Drones always carry a minimal amount of payload and hence require a low weight power receiving system. The integration of 3 by 4 antenna array with the power management circuit makes it of minimal weight which is effective for UAVs. The distance taken into consideration is from 1 to 6m which works in relation to the power transmitted. Far-field transf...

The implementation of flexible and wearable textiles in antennas is measured as a milestone of advancement due to the recent curtail of wireless devices. Among the various antennas, flexible and wearable antennas are broadly identified by t h e i r flexibility, durability, compactness and reconfigurability. As a consequence of this, the fabrication progress and materials used in the wearable and flexible antennas are unconventional and they are needed to be figured out and addressed. In this paper, we discussed on the matter of fabrication and measurement approach and some related issues of flexible and wearable antennas in detail.

Energy harvesting is done from those natural resources which are inexhaustible. So that it is more convenient than wall plugs and batteries which are costly and need replacements. Now, with ubiquitous computing requirements in the fields of embedded systems, wireless sensor networks and low power electronics such as MEMS devices, an alternative source of energy is required. Also with the limited capacity of finite power sources and the need for supplying energy for a lifetime of a system, there is a requirement for self-powered devices. The process of extracting energy from the surrounding environment is termed as energy harvesting. Energy harvesting, which originated from the windmill and water wheel, is widely being considered as a low maintenance solution for a wide variety of applications. There are various forms of energy that can be scavenged, like thermal, mechanical, sola...

This work is designed using lumped components and distributed components with RT/Duroid-6010 substrate with εr = 10.8, Loss tangent = 0.002 and h = 1.27mm along with a microstrip with t = 0.035mm using the T-network. The three-Stage stepped impedance microstrip low-pass filter is compared with the three-stage microstrip stubbed low-pass filter on the basis of design approach and an additional comparison has been made by changing the substrate to FR-4 with εr = 4.3, Loss tangent = 0.025 and h = 1.27mm along with copper (annealed) as a microstrip with t = 0.035mm. The simulation is worked out on the CST-Design Environment where the schematics are used to design the filter and the responses are plotted for the same designs. The originality of this work would be to show the change in sharpness, group delay along with the change in parameters upon changing the materials.

In the current scenario, no study was found where collectively all the available materials and their properties could be discussed including their pros and cons features. This chapter identifies various available materials on the basis of their characteristics, availability, and the methodology of fabrication being involved along with their corresponding properties. Post detailed study and analysis done in this research enabled us to broadly classify the materials as conductive and substrate materials. This brings to the understanding that earlier no such broader classification was made available, and hence, a comprehensive study would provide us better information availability on various wearable antenna materials.
