The radiation and frequency characteristics, together with the sum and difference performance of the wave front matching (WFM) lens antenna and the shaped lens (SL) antenna are studied in this paper. The performances of these antennas are analyzed using finite element method. The Radiation pattern of these two antennas are computed and given, which show that both the antennas have low side lobe level...
A kind of uniform beam shaper which is designed using binary diffractive element and for millimeter wave application is studied in this paper. This kind of beam shaper transforms the incident Gaussian beam into quasi-plane beam with uniform amplitude. Finite element method combined with c simulated annealing method is used to design this kind of beam shaper. A kind of quasi-optical beam divider is...
This paper focuses on the design and analysis of several kinds of dielectric lens antennas and their application at millimeter waves and sub-millimeter waves. The lenses analyzed include refractive lens and diffractive lens such as hyperbolic lens antenna, binary diffractive lens antenna and shaped lens antenna. Our purpose is to optimize the performance of the lens antenna so as it has low side lob...
