Antennas are a ubiquitous part of electrical engineering and the engineering of antennas continues to be extremely important due to the move by designers towards ever increasing electromagnetic frequencies. Effects of a dielectric lens, including its geometry and material properties, placed near an antenna on its directivity and gain is presented. A conceptual model for delivered power and directivity is developed and demonstrated through simulation. A homogenous dielectric material lens is analyzed using the Drude-Sommerfeld model to calculate both the permittivity and permeability when coupled with a 10.4GHz circular patch antenna.
