The sub 3 GHz spectrum has been exhausted but the 3-300 GHz spectrum remains underutilized and specially the 3-30 GHz spectrum is referred as the Super High Frequency (SHF) and the 30 – 300 GHZ spectrum is referred as the Extremely High Frequency (EHF) or as the millimeter 9mm) wave band. This paper presents a modified compact 2x4 slotted array antenna using RT5880 substrate with substrate thickness of 1.6 mm, dielectric constant of 3 and tangent factor of 0.0009 resonating at 27.7 GHz. The designed 2x4 slotted array antenna is simulated using HFSS and the simulation results show that the gain achieved is 5.3 dB with return loss of -14.77 dB, and the bandwidth achieved is 280 MHz. The modifications done are the change in the substrate from RT3003 to RT5880 design, substrate height is changed and the removal of the slot in the ground plane as compared to the existing design. This resulted in a dimension reduction by 8.6%, with patch size of 28mm x 28mm. Future work, is to focus on achieving high gain and high bandwidth considerations of 5G network.
