Since Nikola Tesla discovered wireless power transmission, it has become a very interesting topic of study in the antennas and wireless propagation community. Various aspects and applications for wireless power transmission are studied today, a few of which are investigated in this work. First, various antenna geometries are analyzed for radiative near-field wireless power transfer in terms of electrical field strength. It is determined that the meander antenna is ideal for maximum power transfer in its radiative near-field region, contrary to its far-field behavior. Next, in the application of radio frequency identification, a directive, UHF RFID tag antenna is designed for pavement embedded applications. The antenna covers 72% of the US required bandwidth (902 – 928 MHz) in measurement and has maximum directivity and read range of 7.38 dBi and 14.2ft (4.3 m), respectively. Although the transmitter and receiver antennas' designs are essential parts of the wireless system, power loss to the wireless channel is another critical factor to consider in ensuring the receiver antenna receives the maximum power. Friis transmission equation is studied in detail, and a section of the Georgia Southern University campus is considered for full cellular coverage in the GSM frequency range. Additionally, using the genetic algorithm in parallel, the optimal position for a 60-GHz wireless router is determined to obtain maximum WIFI coverage in a specific house. Finally, the design procedure for a size-reduced, 15-element Yagi antenna is discussed. A comprehensive comparison is conducted demonstrating the importance of the antenna design, with its similar performance to the full-sized Yagi antenna, while its elements are reduced by 45%.
