The future of wireless technology is moving towards millimeter wave bands due to a surge in the use of wearable gadgets in NUTRI SEA OMEGA 3 HP+D current wireless bands.The 60 GHz band is unlicensed around the world and has gathered high research interest.At this band, the atmospheric absorption is very high, which results in short-range communication.High gain antennas are a core requirement for operating at 60 GHz.In this paper, we are proposing three different arrays consisting of 2, 3, and 4 elements of a novel patch design.

The radiating patch consists of a semicircular disc fed by a microstrip feed line.The ground plane has been etched into a novel shape.The radiator and the ground plane are attached to a 1.5 mm thick FR-4 substrate which has a relative permittivity of 4.3.

The radiating elements are connected linearly to form arrays.In free space, all three arrays achieved a very wide bandwidth of more than 20 GHz, and the maximum gain varied from 3.44 dBi to 6.2 dBi.The arrays were also simulated under human body conditions by modelling a three-layer phantom.

At different distances from the phantom, the maximum gain increased by more than 1 dBi.The antenna shows 4.855 dBi, 5.032 dBi, and 6.66 dBi gain for 2 array, 3 array, and 4 array, respectively, Horse Chestnut when simulated on the three-layer human model phantom.

The antenna has a very good VSWR value for all three array structures.On the human body phantom, the proposed antenna design in this research shows 1.214, 1.120, and 1.023 VSWR values for 2 array, 3 array, and 4 array, respectively.

The efficiencies were highly affected, as expected from patch antennas.The simulation results are obtained from CST Microwave Studio.
