This paper presents a proposed Circular-shaped Antenna array for millimeter-wave application. The proposed antenna is designed to operate at mm-wave frequency of 17 GHz. Circular antennas give good return loss, and better gain and directivity. The main aim of using the array is to improve the gain of the antenna. Inset feed technique is used to design the antenna. The size and feed technique are determined by design formulas. The simulation results show a good return loss (reflection coefficient) of -55.297 dB which is way below the benchmark of 10dB and a bandwidth of 1.79 GHz (16.42 – 18.21 GHz). The gain and VSWR results are 8.684 dB and 1.0034 respectively at 17.29 GHz frequency. The CST software is used for the simulation.
