Millimeter-Wave Design of Stacked Micromachined Patch Antennas

Performance especially bandwidth improvement of a Finite Coplanar Waveguide-Microstrip Line(FGCPW-MS) fed aperture-stacked micromachined patch antenna operating at 35 GHz is presented. The effects of varying several key physical parameters of the structure are investigated to get the maximum improvement in bandwidth and HFSS software is used to optimize this model. The results show that bandwidth of 11.8%, gain of 7.8 dB and efficiency of 71% have been achieved .Compared with conventional microstrip antenna, such an antenna can significantly improve its performance in bandwidth,gain and efficiency and it is also easy to integrate with other active components.
