Millimeter Wave Microstrip Patch Antenna for Next-Generation Mobile Communication Networks

The fifth generation (5G) mobile communication network is expected to accommodate the communication requirements of billions of connected devices by enhancing speed, latency, size and cost. Millimeter wave (mmW) technology a candidate 5G technology requires special and well-designed antennas to power its transmissions. Microstrip patch antennas (MPA), which are popular due to their low profile, lightweight, tiny size, low cost, and simple fabrication, could meet these requirements. The proposed MPA is designed and fabricated on a Rogers RT Duroid 5880 substrate with a dimension of 6.3 × 7.24 × 0.5 mm³, a dielectric constant of 2.2 and a tangent loss of 0.0009. The proposed MPA at 28 GHz with a measured return loss of -21.37 dB, measured impedance bandwidth of 2.685 GHz and directivity of 10.02 dBi. The proposed antenna has significantly improved gain and bandwidth as compared with the previous literature due to its compact size which can be used for 5G mobile communication.
