Abstract

The design of a hemispheric dielectric lens antenna using the effective medium theories (EMTs) is presented in this paper. The hemispheric dielectric lens antenna is made of low loss Poly Tetra Fluoro Ethylene (PTFE) with cylindrical air-filled holes drilled. In order to realize the necessary lens dielectric constant the lens antenna is well described by using the Asymmetric Bruggeman´s (ABG) formula of the effective medium theory. The antenna is fabricated by drilling numerous holes with diameters sufficiently smaller than the wavelength in the host material. Measured dielectric lens antenna radiation characteristics are in good agreement with the simulated radiation characteristics results.
