Miniaturization of Microstrip Patch AntennaS (MPAS) is a very challenging field to investigate due to the increasing interest in integrating such antennas in MMIC circuits. The conventional dimensions of MPAS are around a half waveguide wavelength. Several miniaturization techniques are appearing to reduce such dimensions. These techniques can be classified in: use of high permittivity substrates, use of magnetic substrates, increase electrical length, short-circuits, superstrates and combinations of them. A novel circularly polarized coaxial fed rotated stacked patch antenna is proposed and its performance characteristics are presented in this paper. The antenna consisting of four parasitic patch, each one being rotated by 30 deg relative to its adjacent patches.
