Design & Optimization Procedure of 5G Millimeter-Wave Antenna Integrated in Mobile Devices

This paper proposes a design and optimization procedure of 5G millimeter-wave (mmWave) antennas integrated in mobile devices. Radiating element’s shape and phase offset between two orthogonal components are investigated, and the study suggests that these parameters can be optimized for wireless performance while complying with RF exposure regulatory. Furthermore, by combining simulations and measurements, regulatory process for commercial mobile devices can be implemented with shorter time, lower cost, and higher effectiveness.
