The present scenario that demands a high data rate by the consumers in wireless communication has imposed a challenge in the present market. Therefore, millimetre wave technology is attracting the interest of researchers and industries. This paper proposes a rectangular planar microstrip antenna with slots in radiating elements as well as in the ground plane. The proposed structure has been designed, simulated and fabricated at a centre frequency of 28 GHz using 5880 RT duroid as a substrate, which has a relative permittivity of 2.2, loss-tangent of 9x10-4, and thickness of 1.6 mm. By performing the simulation using HFSS Ansys Software and also fabrication and testing, the proposed design attains a maximum gain of 8.735 dBi and a frequency band-width of around 2.815 GHz. The impedance bandwidth response ranges from 26.75-29.565 (10.1%) below the -10 dB line of the S11 plot. The proposed antenna is compact with dimensions of 2.19 x 3.95 mm and has wide bandwidth along with high gain, hence is a good candidate for mm-wave applications besides several innovative antenna-based gadgets. Measured S11 and VSWR results are in consistent with the simulated ones.
