High Gain Microstrip Quad Array Antenna for Sub-6 GHz 5G Applications

Abstract This paper depicts a microstrip array antenna suitable for the 5G applications comprised of four rectangular patches organized in a symmetrical structure. The microstrip quad array antenna is designed and simulated utilizing Sonnet Suites software. The proposed design is manufactured with implementing Rogers RO3006 dielectric substrate (ε_r = 6.5) due to the low tangent losses of the substrate. Moreover, the simulated and measured results display the successful fabrication and the design process. The input match (S_11) is slightly higher for the simulated design in comparison to the measured results with approximately − 18.63 and − 13.66 dB respectively. By Implementing the quad structure the gain is increased. The Simulated gain is approximately 13.55 dB whereas the measured gain is around 13.06 dB at the operating frequency of 5.53 GHz. Lastly, the design is inexpensive and the utilized geometry is somewhat simplistic alleviating simulation and manufacturing issues for the proposed design..
