Description
A design of a flat dielectric lens is presented in this study to enhance directivity
of a pyramidal horn antenna. The horn antenna is proposed to cover frequency
of medical imaging system, which is between 5 and 6 GHz, and dielectric lens
is designed based on phase correction techniques. The spherical waves
produced by conventional horn antenna is being transform to planar waves by
resorting flat lens in order to achieve a highly directive radiation in the farfield
region. This is done by drilling numerous holes with different diameters
through the dielectric material to produce different phase delay. The radiation
characteristics of the lens are simulated using CST Microwave Studio and then
compared with measured results. The results showed a good performance for
radiation pattern when the lens is attached. This proposed design shows a
significant increment of sidelobe level and 3-dB beamwidth between 5 and 6 GHz.
