Hemispherical dielectric lens antennas can be designed to present multifunctional operation. Simple and efficient mathematical modeling to design these structures is presented. The constructing technique is based on the lens material and the desired operational frequency of the dielectric lens antennas. The analytical developed model was compared with both complete wave numerical simulations and practical experiments. The results indicate that the proposed equations to build hemispherical dielectric lens antennas are adequate for different operational frequencies and also for different dielectric lens materials.
