In this paper, Triple Band Rectangular Microstrip Antenna with Two Vertical Rhombus Shaped slot (TBRMA2VRS) is designed and developed for S and C band frequency applications. The triple bands are obtained by etching two rhombus slots on the patch surface. The impedance bandwidth of secondary band is enhanced from 2.06% to 8.54% by replacing the two rhombus slots. The radiation patterns measured on microwave bench setup for the proposed antennas are found to be broadsided, linearly polarized and are similar to the pattern of conventional RMSA. The antenna design procedure and results are presented and discussed.
