This article elucidates a high gain dual band ear bud shaped patch antenna with mm wave technology. The pivotal characteristic of this design is to provide higher gain and less interference at higher frequencies. It operates at a frequency of 40.59 and 52.002 GHz. The major advantage of this design is that it produces the circular polarization in entire band of frequency; moreover this antenna is useful for under water communication. The proposed design introduces two splits, imprinted at the walls of patch to get a wide band. For an optimal design, a future antenna parametric analysis was carried out. The proposed design is developed with the aid of HFSS software; we measured major parameters S11, VSWR, gain and radiation patterns in free space and underground environment. In the results, the predicted antenna radiation pattern is seen for E‐plane and H‐plane at various frequency bands. The gain 3D polar plots and current distribution plots are presented, including a comparison of previous work to the current work. We assure that the suggested design is applicable for under water communication.
I.INTRODUCTION The wireless power transfer is the applications for the ability to transport power over great distances and the discussion of wireless power transmission as an alternative to transmission line power distribution started in the late 19th century. Both Heinrich Hertz and Nicolai Tesla theorized the possibility of wireless power transmission. Tesla demonstrated it in 1899 by powering fluorescent lamps 25 miles from the power source without using wires (1) Despite the novelty of Tesla's demonstration and his personal efforts to commercialize wireless power transmission, he soon ran out of funding because it was much less expensive to lay copper than to build the equipment necessary to transmit power through radio waves boundaries without the need for transmission lines. Loads using a high-frequency resonating air core transformer to develop the frequency from 50hz to 40 kHz for transferring power over a distance of 3cm wireless power transfer can make a remarkable change in the field of electrical which eliminates the usage of conventional copper cables and current carrying wires. Based on this concept, the project is developed to transfer the power within a small range. The patient is required to be operated every year to replace the battery. This project is built upon using an electronic circuit that converts ac 230v 50 Hz to ac 12v, high frequency. The output is fed to a tuned coil forming as primary of an air-core transformer. The secondary coil develops a voltage of hf 12volt. Thus, the transfer of power is done from the primary (transmitter) to the secondary, which is separated with a considerable distance. Therefore, the transfer could be seen as the primary transmission and the secondary receives the power to run the load. The goal of the project was to evaluate and study the wireless power transfer technologies and physics behind it. The design and implementation of the wireless energy transmission system prototype and its implementation in the next floor innovative floor was the main plan. It was crucial for next floor to integrate advanced technologies into their floor system in order to make it really "smart" and innovative and wireless power transfer was one of them. WPT is a very broad though relatively new technologyalmost 80% of references are dated later than the year 2010; hence, the scope of the project was limited to implementation of the inductive power transfer mode.
