Planar inverted F antenna (PIFA) is mainly fit for mobile devices. PIFA is mostly designed for dual band frequencies as it is capable of covering wide range of wireless services. This in turn helps in making it acceptable for designing mobile devices. Sizes of ground plane as well as PIFA’s position with respect to ground plane actually effect the performance of PIFA. For example, placement of PIFA at corner of ground plane shows good radiation pattern. Major prerequisite of 5G is nothing but the capability to enhance data volume to every single user, while supporting majority of mobile users as well as new maneuvers. The best part is advanced antenna array technologies are able to meet such requirements. Although PIFA antenna has gained popularity in designing mobile handsets, because of light weight, lower cost as well as higher directivity, PIFA antenna Arrays have been proved to be strong foundation for future 5G Mobile Communication Systems as PIFA Arrays provide better gain than single PIFA antenna in same frequency band. Current work presents a comprehensive study on so far impact of PIFA as well as PIFA Array in providing infrastructure for future mobile innovations suitable for 5G communication.

With recent advancements in magnetic field simulation speed and capacity, as well as in power electronics, the area of wireless power transmission has grown considerably. Electric cars are being investigated as a possible substitute for internal combustion engine-powered vehicles in the future transport sector, particularly for CO2 reduction and alternative energy purposes. However, because to the vehicle's high weight, large capacity, and restricted driving range, many critical problems must be addressed. The article introduces the novel on-road dynamic wireless charging system for electric vehicles. Repowering technique for rechargeable vehicles is categorized as conductive or wireless, fixed or dynamic, and slow or rapid. In this paper, a concept in which an electric car is charged while in motion, without the need for a halt. Furthermore, a green and creative method to generate energy for the purpose of charging these cars is being proposed.
