Design of Maximum-Gain Dielectric Lens Antenna via Phase Center Analysis
Abstract
In this work, a method is presented to maximize the obtained gain from millimeter-wave (mm-wave) lens antennas using phase center analysis. Commonly, for designing a lens antenna, the lens is positioned just on top of the antenna element which is not capable of providing the maximum gain/aperture efficiency. A novel solution method is proposed where the lens will be placed at a distance calculated using phase center analysis to produce the maximum gain from the system. A mm-wave microstrip antenna array is designed and the proposed method is applied for the gain enhancement. Simulation results suggest that the propose scheme obtains around 25% gain enhancement compared to the traditional method.
