Design of Wideband Microstrip Patch Antenna Array with Improved Feedline for 60GHz Wireless Applications

The article presents a wideband microstrip array of patch antenna maximized for 5G short wave applications, containing an improved feed line. The presented antenna dimensions are ideal for millimeter wave frequencies, featuring a wideband array with a slot-loaded on the ground and fed through a 50-ohm microstrip line. Its design employed Computer software technology (CST) Microwave Studio, considering a relative permittivity of 2.2, a loss tangent of 0.0009, and a height of 0.254mm on a Rogers RT5880 dielectric substrate. The article presents a proposed wideband microstrip patch antenna, along with simulation results for reflection coefficient, VSWR, and 3D field strength pattern. The modeled array of an antenna expresses a reflection coefficient of -42.315 dB at a specific millimeter frequency of 60 GHz, making it suitable for short-wave applications with an enhanced microstrip feedline.
