Design and Investigation of a Compact 3D MMIC Patch Antenna for mm Wave Applications

This work focused on the design, characterization and investigation of GaAs based multi-layered compact 3D MMIC based antenna. Different patch antennas were designed and characterized along with its S-parameters. The proposed models of multi-layered patch antennas use V-shaped feeder line or a spiral transmission feeder line. The newly propose planar antennas are more compact in area compared to using the normal planar feeder line; this design approach allows to have wider bandwidth, better input return loss and a slightly lower resonance frequency.
