A new type of Rectangular Microstrip Antenna with Rhombus Shaped slot (RMARS) is designed and developed for high microwave frequency applications. The dual bands are obtained by etching rhombus slots on the patch plane. The formation of secondary band does not influence the resonant frequency of primary band. The impedance bandwidth of secondary band is enhanced from 2.06% to 18.54% by replacing the rhombus slots. The radiation patterns of the proposed antennas are broadsided linearly polarized and are similar to the patterns of conventional RMA. The design procedure and experimental results are presented and discussed.
